1. I will not introduce you much to O & O Software GmbH, the manufacturer of the O & O Defrag program and many other useful programs. Such as O&O ShutUp10 to disable surveillance in Windows 10, I talked about it in the article, there is more than one way to do it, and they include a method with the O&O ShutUp10 program.
  2. O&O Software GmbH was founded in 1997 in Berlin by Oliver Falkthal and Olaf Kehrer. The idea for the name "O&O" originated as early as 1991 in the form of O&O Systemtechnik GbR, a company offering software specifically for students while the two founders were still studying. The name "O&O" appeared spontaneously, as the names of the first founders begin with the letter "O". In 1998, on February 10, to be precise, O & O Defrag V1.0 was released to the public, at the same time O & O Software GmbH was born.
  3. File defragmentation is another item on the list for the speed of computing devices. Defragmenting files is easier to say to clean up your hard drive or ssd drive. I repeat, not cleaning unnecessary files or deleting old files and cleaning the registry in the trash, namely the order after cleaning so that everything is in its place. When the operating system writes files to a disk or overwrites an existing file with new information, one file, as shown in Explorer, can visually lie in parts in different corners of your disk. Of course, the system will not show you such a mess, since then you definitely couldn’t find anything, but then, when you re-access it, it starts collecting this file in order to open it and show everything that was saved in it in full. Such actions take a lot of time, given that the system is working and, in addition to your files that you need at the moment, it can index others and so on. Actually, what am I talking about defragmentation, I told all this in the article defragmentation in this article, if you go there is a more detailed description with an example of why this happens with files and why the mess. And in this article on this page, I wanted to tell you about the excellent O&O Defrag 22 file defragmenter, besides, it can also defragment the system partition, which not every defragmenter can do. And the order on the system partition is, as I said earlier, that defragmentation is an increase in the performance of your system. In addition to this good function, the O&O Defrag 22 defragmenter has a number of huge functions that it can boast of, for example, so that you do not defragment the entire disk partition at once, the O&O Defrag 22 defragmenter will do this immediately when it writes the file to disk, placing it in place immediately. Actually, what I am telling in parts, let's move on to a step-by-step review of O&O Defrag 22 and at the same time understand how to work with it:

    4. Optimizing SSDs and HDDs with the new SOLID method in O&O Defrag 22.

  4. If anyone knows this defragmenter or uses it, then version 22 has new features that you should definitely talk about, and especially this is the SOLID method, which is described on the company's official blog. Latest version of O&O Defrag 22 with new method to optimize SSD performance and lifespan.

    5. SSD controller

  5. SSD - Spreads files into separate file chunks on save, in each case in the following free and appropriate sections of memory called pages. I explain why this behavior slows down not only the classic hard drive, but also the SSD eventually leads to an unreasonably early failure of the storage medium. SSD defragmentation is not mandatory as it is still popularly stated, but on the contrary, the average life of an SSD is extended by defragmenting using the new SOLID method.

    6. SSD Structure

  6. An SSD is made up of cells, pages, and blocks. A cell can have multiple bits. The manufacturer marks this cell as either SLC, MLC, or TLC. SLC - SingleLevelCells (1 bit per cell), MLC - MultiLevelCells (from 2 bits per cell, but mostly exactly 2 bits, and TLC - TripleLevelCells (3 bits per cell). Pages are made up of cells and are usually 2 KB - 4 KB Blocks are then made up of these pages and are typically 128 KB - 512 KB in size.

    7. How does an SSD store data?

  7. Writing data to an SSD is mostly done in Pages. However, these pages should not be written with data, even if they have the same content. If these pages are written with data then the corresponding block must be deleted immediately before any new data is written. However, when writing new data, no block can be selected whose other pages also contain data. The SSD controller can see that other pages contain data but cannot see which file they belong to. In order not to accidentally damage an important file by deleting data from it on a block, you need to look for an absolutely free block to save data.

    8. Why is the fragmentation problem related to SSD?

  8. Files are often stored in chunks (fragments) on disk or in the file system. The size of the fragments depends on the cluster size of the corresponding file system (usually 4 KB in NTFS). Suppose the block on the SSD is 128 KB and a file (128 KB) that is split into 32 fragments is to be saved (each fragment will be 4 KB in size). In the worst case, this should be stored on 32 different blocks. If there was only one fragment in this file, one block would be enough. The problem is writing such a fragmented file: The controller has to find 32 different blocks and, in the worst case, delete them all. It then has to write those 32 blocks as well, and this happens every time the file changes too! It's actually being rewritten!

    9. SOLID is a completely new defrag method for SSDs and hard drives.

  9. SSDs store file fragments in many blocks, this memory behavior directly affects the performance and life of the SSD. To counteract wear and at the same time optimize the performance of SSDs, O&O Software has developed a new SOLID defragmentation method. Using the SOLID defragmentation method, these distributed portions of files are defragmented so that in the future, significantly fewer memory cells need to be read and written when a file changes. As a result, SSDs are faster because the number of reads and writes is reduced by defragmentation. In addition, premature wear of the SSD and of course the conventional hard drive is prevented as fewer blocks need to be erased and overwritten than before defragmentation with SOLID. To read a sample file there is no need to first access and read 32 different blocks but only one. Here comes the optimization!

    10. The most complete setup view for all your drives.

  10. A positive side effect of developing the SOLID defragmentation method was found in tests on classic hard drives. It is the most resourceful and hardware-based defragmentation method with optimal results and sets a new standard for defragmentation. As we mentioned above, files are also fragmented on the SSD. The data is often spread over more memory cells than necessary. Defragmenting an SSD using our new SOLID method can reduce the number of cells used to store parts of a file to a much smaller number.

    11. An overview of the O&O Defrag 22 defragmenter.

  11. Installing the defragmenter is not difficult, the usual installation in Windows with a minimum of settings and offers to choose the installation of modules or the like is not there, the child can handle it and therefore I will skip the point. If you have any questions about this, then write at the end of the article in the comment system. The first launch of the defragmenter and a nice external window:

  12. The defragmenter needs to be launched for the first time and let it defragment the sections, only then it will be possible to schedule actions so that it does the defragmentation itself, it also defragments the file immediately upon recording, so that later it does not perform a full defragmentation. For a simple PC user, the default settings will suffice. On the main page and the first tab called O&O Defrag there is a "Quick Start" icon. Now I will show what it contains and how to configure the defragmentation program. Press "Quick start" and proceed to view what contains or what settings the "quick start" window contains, picture below:

  13. The first thing is a checkbox that activates the rest of all the settings - "Schedule automatic defragmentation". Next comes the choice of one of the three options.
  14. 1.) Automatically optimize hard drives in the background. This means that the optimization will constantly monitor and perform the necessary operations at any time. This is the most normal option but requires computer resources, although not much.
  15. 2.) Optimize when the computer is not in use (when the screenserver is active). This item will start optimization when the computer is idle and the screensaver turns on.
  16. 3.) Defragment disks at the specified time. In this option, you set the time at which the defragmentation will start, but if the computer is turned off, the defragmenter will not be able to start.
  17. Next comes "Additional automatic optimization" and see below what you can configure which options.
  18. 1.) Optimize SSDs with TRIM feature. This feature is enabled by default and is supported by Windows 10, 8 and Windows 7. TRIM is essential for maintaining the performance of SSD drives.
  19. 2.) Wipe free disk space. This means that after deleting or moving a file, this area is overwritten with zeros to make it unrecoverable.
  20. 3.) Overwrite dynamically expanding disks regularly. This feature is suitable for virtual machines, or disks that, as they fill up, expand due to some other space.
  21. In this section of the tab "After defragmentation, perform additional optimization steps."
  22. 1.) Wipe free space after every defrag. I think it’s understandable, I told you a little higher, take the information from there.
  23. 2.) Optimize disks with dynamically allocated capacity after each defragmentation. Not long ago, he also told everything clearly about such discs. The difference was just previously told during optimization and this option after defragmentation.
  24. After the settings are done, click "ok" to confirm the settings. After the window closes, the defragmentation of your disks will begin immediately, the picture is below:

  25. Then you can not touch the program and when you save files and do other operations with them, the defragmenter program itself will arrange the files in the right order.

    26. If the computer resources are not enough.

  26. If the computer resources are not enough for the defragmenter program to work in the background. Then you can set the settings for how much the program, in percentage terms, should load the processor and hard disk for defragmentation tasks when accessing it. This can be done by clicking on the first tab O&O Defrag of the main window of the defragmenter, the "Settings" icon, picture below:

  27. In the new window that opens, go to the "O & O ActivityMonitor" tab and the first section from the top "Download" just offers three options.
  28. 1.) Limit the processor load from O&O Defrag - then follows a window with percentages and in it you can set how much the defragmenter program can take, or rather, take the processor as a percentage for your needs. The lower the percentage, the easier it will be for the system, but then the time for defragmenting files and the program as a whole will increase.
  29. 2.) Do not execute the task if the processor load is higher - this parameter is also set as a percentage, as soon as the processor is loaded more than the specified percentage, the defragmenter program will stop working (task) and pause until the processor load drops below the specified percentage in the settings.
  30. 3.) Do not execute the task if the hard disk load is more - This option also works like option 2. but here the disk access is configured and the percentage set in the settings will disable the task (work) if the disk access goes beyond the set percentage.
  31. The section on this tab "Programs" will also be useful if you add any other program to it and when you start it, the defragmenter will stop the task (work) until the program specified in the defragmenter settings completes its work. You can add it by clicking on the cross and in the explorer window that opens, select the file of the desired program with the .exe extension. After that, the selected program will be displayed on this defragmenter tab. You can remove a program by selecting it and pressing the minus button. If someone did not find the + and - buttons, I showed them with an arrow in the picture below.
  32. The last setting option on the "O&O ActivityMonitor" tab is "Power", this setting is suitable for laptops, to extend laptop battery life, check this setting. After that, as soon as the laptop is disconnected from the network, the defragmenter program will stop working in order to save battery power. Below is a picture that shows all these settings mentioned above.
  33. The O&O Defrag program is so flexible that it will satisfy everyone and the performance really improves, try it yourself. You can download or go to the manufacturer's website using the links below.

» I have already touched on the topic of disk defragmentation. O O Defrag Professional is a very efficient and powerful defragmentation software for hard drives, flash drives and solid state drives.

The main advantages of O O Defrag Professional edition include the following:

  • five defragmentation methods.
  • Full defragmentation of the hard drive in almost any case.
  • Working with external USB drives.
  • Support for 32 and 64 bit versions of Windows 7, Vista, XP.
  • Convenient, intuitive interface.
  • The ability to obtain a large amount of information about the disk regarding defragmentation.
  • Ability to run defragmentation according to plan.
  • Possibility of parallel and sequential execution of operations on disks.
  • Disk defragmentation when the operating system boots.
  • Automatic disk optimization.
  • Flexible settings for excluding files from defragmentation.
  • Activity monitoring.

There are a lot of opinions about the importance and necessity of disk defragmentation. Considering a large number of factors (type of drive, file system, cluster size, size of stored files, operating system, frequency of disk use, and so on), hard disk defragmentation will have a different “utility character”. Now (mid-2011) there is an active transition from hard disk drives to solid state drives (SSD). Flash drives are the most popular devices for "transferring information in your pocket." For hard disk drives, fragmentation has a more detrimental effect on performance than for solid state drives and flash drives (memory cards). However, for SSDs, disk defragmentation plays a "wear-reduced role". Many articles have already been written about this.

It is worth noting the specific area of ​​\u200b\u200bthe "hard drive" - ​​the Windows registry. To check and defragment it, I recommend the TweakNow PowerPack system utility.

The review will include the latest, at the time of this writing (07/19/2011) stable English version of O O Defrag Professional 14.5.543 x64 (Operating system - Microsoft Windows 7 Ultimate SP1 (build 7601), x64).

System requirements for O O Defrag Professional 14.5.543 x64. O O Defrag Professional edition does not impose special system requirements on the system. If your PC meets the system requirements of the operating system installed on it, then O O Defrag Professional will work.

  • 50 MB free disk space for installation.
  • Access right Administrator level.
  • Supported operating systems: Windows 7, Vista, XP. 32 and 64 bit versions are supported.

Main window O O Defrag Professional

The main window of O O Defrag Professional (figure below) can be roughly divided into three areas.

  1. Menu.
  2. Disk table.
  3. Disk information.

The menu area is visually divided into five groups.

  1. defragmentation.
  2. Reports.
  3. File system.
  4. Options.

Region Disk table by default contains twelve columns.

  1. Disk. Volume letter.
  2. Name. Volume label.
  3. Action. Displays the status of the action being performed on the drive.
  4. Status. Percentage of completed action.
  5. Total files.
  6. Fragmented files.
  7. fragmentation percentage.
  8. The size. Disk size.
  9. Free. The amount of free disk space (in gigabytes).
  10. File system.
  11. The current file or folder. The full name of the file (folder) on which the action is currently being performed.
  12. Time left. The time until the completion of the operation.

It is possible to sort in direct or reverse order by any of the columns, arrange the columns in the order convenient for you. If necessary, you can hide or add some columns (picture below) or reset the disk table settings to default. And also specify the alignment of the contents of the disk table (left, right, center).

To area Disc Information(picture below) hard disk defragmentation is presented in a visual form.

Contains five tabs.

  1. Type of clusters.
  2. Tasks. Tasks will be discussed in detail later in the article.
  3. Reports.
  4. Disk status.
  5. File status.

Tab Type of clusters(figure above) contains a graphical representation of the disk file system and a color legend. If desired, you can change any of the colors of the legend. The O O Defrag Professional edition legend contains the following items:

  • Free.
  • Condensed.
  • Defragmented.
  • Fragmented.
  • Reserved for the file system.
  • System.
  • Report files.
  • Blocked.
  • In the process.
  • Directories.

All of them display the belonging of a particular place on the disk to different types of files (or directories). You can customize the display of the graphical representation using the following options.

  • Classic representation of clusters. Will remove the gradient from the clusters. Make them one color.
  • Shadow. Add or remove the shadow cast by each cluster.
  • Cluster size. You can change the color cell display size (diagonally in pixels) to 3, 4, 5, 6, 8, 10, 12, 14, 18.

With a smaller cluster size, you get a more detailed view of the volume's file system structure. Since, for example, with a color cell size of 18 pixels (figure below), one fragment can contain many different types of files. Information about the content of a particular colored cell can be found by double-clicking on it.

The figure above shows the display of cells in a non-classic way, with a shadow, a gradient and a size of 18 pixels. For example, I will show in the figure below the display of cells in a classic form without a shadow and a 3-pixel gradient. I will also give information about the content of one such cell.

On the tab Reports(picture below) displays all available volume reports.

An example of viewing one of the reports in the browser is shown in the figure below.

Tab Disk Status(picture below) displays brief information about the selected drive.

Tab File Status(picture below) contains a table with information about disk files.

It is possible to filter the list of files by the following criteria.

  • fragmented files.
  • Large fragmented files.
  • Fragmented system files.
  • Large system files.
  • Fragmented locked files.
  • Large blocked files.
  • Large files.

You can sort any of the filtered lists forward or backward by the following columns.

  • File name.
  • File size.
  • Fragments. Number of file fragments.
  • File fragmentation percentage.
  • initial cluster. The number of the cluster where the beginning of the file is located.

O O Defrag Professional has options to customize the program window display style (colors), font size, text direction (right to left), and window transparency for Windows 7 and Vista.

Toolbar

defragmentation

Option Fast start(picture below) will allow you to schedule a defragmentation and / or start immediately.

You can specify automatic disk optimization (in the background), disk optimization when the system is idle, or optimization time (day of the week, hour, minute). You can specify the sign of monthly or weekly defragmentation. It is possible to tell O O Defrag Professional to check the disk file system for errors before defragmenting.

Analysis allows you to perform a forced analysis of the state of the selected disk. Before starting defragmentation, O O Defrag Professional will definitely analyze the selected volume. After the analysis, a graphical representation of the cluster map will be available to you.

In O O Defrag Professional edition 14.5.543 x64, you can choose one of five disk defragmentation methods.

  1. High-speed.
  2. Space.
  3. Full/Name.
  4. Full/Date modified.
  5. Full access.

I took the description of defragmentation methods from the help file (in English) installed with the program. The translation is not literal with its own comments and interpretation.

The speed method uses less (compared to other methods) amount of RAM. It gives good results even on computers with low RAM and little free disk space. The method is to try to fragment and merge files in order to optimize free space. This method is recommended in the following cases.

  • Initial defragmentation of your system's hard drive.
  • Servers with very large disks (for example, larger than 4 terabytes).
  • Computers with a very large number of files (greater than 3,000,000 files).

Method Space. Consolidates its data so that the amount of contiguous free space is as large as possible and reduces the chance of further fragmentation. This method is recommended in the following cases.

  • Initial disk defragmentation of your system.
  • Computers with "weak" hardware and not a lot of free disk space.
  • Servers with large disks (for example, larger than 1 terabyte)
  • Computers with a large number of files (more than 100,000 files).

Method Full/Name previous. However, it provides a larger percentage of the file system performance boost. In addition to defragmentation, it reorganizes the structure of files. Files are sorted alphabetically from beginning to end of the disc, and this results in quick access to files in the directory. When Windows boots up, most of the system files will be read in sequence from the WINDOWS folder and system32. This will reduce system startup time. This method is especially recommended for computers that rarely change files. This reduces the rebuild time required for each defragmentation. This method is recommended in the following cases.

  • All types of servers and workstations.

Method Full/Date modified. A method that is more demanding on hardware resources and takes longer to complete than high-speed and method Space. However, it provides a larger percentage of the file system performance boost. In addition to defragmentation, it reorganizes the structure of files. The files are sorted according to the date they were last modified. Files that have not been modified recently will be placed at the beginning of the disk, and recently modified files at the end. This method is good for file servers or database servers that contain files that never change (such as system files) and files that change frequently (such as database files). This method allows future defrags to run as quickly as possible, as only some files need to be checked and defragmented. This method is recommended in the following cases.

  • For regular defragmentation.
  • Computers with "strong" hardware and plenty of free disk space.

Method Full/Access. A method that is more demanding on hardware resources and takes longer to complete than high-speed and method Space. However, it provides a larger percentage of the file system performance boost. In addition to defragmentation, it reorganizes the structure of files. Files are sorted by the date they were last accessed. Files that are rarely accessed are placed at the beginning of the partition. Files accessed frequently go to the end. Rarely used files are defragmented and not moved in the future. This method allows future defrags to run as quickly as possible, as only some files need to be checked and defragmented. This method is recommended in the following cases:

  • Maximizes file system performance on servers.
  • For regular defragmentation.
  • Computers with "strong" hardware and plenty of free disk space.
  • All types of servers and workstations.

DO NOT apply different defragmentation methods to the same disk! This can significantly slow down the defragmentation process, increase the load on the computer hardware and lead to undesirable consequences of file system fragmentation! It is especially NOT recommended to perform different defragmentation methods for automatic optimization in the background and scheduled scans!

As noted earlier, O O Defrag Professional 14.5.543 x64 has the ability to create tasks to automatically perform the defragmentation procedure. To do this, the program has a large number of options. When creating a task, a window will open in front of you (figure below), containing eight tabs.

  1. Main.
  2. Schedule.
  3. Disks.
  4. Files.
  5. Activity monitor.
  6. Settings.
  7. Actions before defragmentation.
  8. Actions after defragmentation.

Let's take a closer look at these tabs.

On the tab Main(picture above) You set the name, description and action with the computer after completing all the tasks. For example, turn off.

Tab Schedule(picture below) You set the schedule for this task. You can choose to run once (with time and day), weekly (with day/days of the week, period from/to and start time of the task) and run when the screen saver starts (it is assumed that you are not working at the computer).

It is possible to specify the maximum duration of the task and repeat the task later if it did not work at the specified time.

On the tab Disks(figure below) it is possible to specify for each disk separately the defragmentation method, the percentage of data defragmentation at which the task should be performed for this disk, assign defragmentation at boot and add disk files to zones (zones will be discussed later in the article).

Files. This tab (picture below) is in turn divided into three tabs.

  1. Excluded files. Files that do not need to be defragmented.
  2. Files to be defragmented.
  3. Files by size. To reduce the disk defragmentation time, you can specify the file size (select from the drop-down list from 100 MB to 5 GB) that will be excluded from defragmentation.

Tab Activity Monitor(Figure below) allows you to set up system busy tracking for a job. It is very comfortable! For example, you have scheduled a full defragmentation of all disks with a file system check before and after defragmentation. And forgot about it. But, for example, half an hour before the start of the task, you left the computer turned on with Pinnacle running, in which a large movie is saved. If you start the task, despite the PC booting, then defragmenting the hard drive and saving the movie can take a very, very long time.

The activity monitor contains settings in which you specify the percentage of CPU and hard drive loading at which the task will not be launched. It is also possible to specify the name of the program, if it is active, the task will also not be launched. You can specify that the task cannot be started if the computer (laptop) is running on battery power. O O Defrag Professional edition 14.5.543 x64 provides an option to "wake up" the computer from sleep or hibernation.

Tab Settings(picture below) contains general options for the job. Such as:

  • Account for removable media.
  • Account for external media.
  • Special disk defragmentation for solid state drives.

You can specify the creation of reports (their number) and the level of detail.

Tabs Steps before defragmentation(picture below) and Actions after defragmentation look the same. In them, you can import a special file with action commands before and after the task is completed.

The created task is displayed in the main window O O Defrag Professional on the tab (picture below).

You can also delete, run and edit the task there.

I took the description of defragmentation zones from the help file (in English) installed with the program. The translation is not literal with its own comments and interpretation.

Dividing a disk into zones allows you to logically distinguish between critical and non-critical data. A special algorithm checks that after defragmentation, the data on the disk is optimally organized. It also checks the placement of files in zones, depending on the settings. For example, system files that need to be accessed frequently and as quickly as possible are separated from other data such as movies and music. This will reduce the percentage of file fragmentation, reduce the time of defragmentation and reduce the load on the system during defragmentation. O O Defrag Professional edition 14.5.543 x64 already has several zones configured. They are optimal for most users. However, you can create your own (picture below).

Setting up O O Defrag Professional edition

The O O Defrag Professional settings window (picture below) is divided into five tabs.

  1. Main.
  2. Disk defragmentation on boot.
  3. Automatic optimization.
  4. Files. This tab is discussed in more detail above.
  5. Activity monitor. This tab is discussed in more detail above.

Main. This tab (figure above) contains the following settings:

  • checking the disk for file system errors before defragmenting and canceling defragmentation if an error is found.
  • Optimize multiple physical disks in parallel.
  • Optimization according to the features of the disk file system.
  • Account for removable media.
  • Account for external media.
  • Special defragmentation for solid state drives.
  • Distribution of files by zones.
  • Enable\disable automatic optimization.

You can specify the creation of reports (their number) and the level of detail. It is possible to display the O O Defrag Professional icon in the taskbar near the clock.

Defragmentation on boot. On this tab (picture below), you can set disk defragmentation when the operating system boots (on each boot, only on the next one).

Tab Automatic optimization(picture below) contains settings that will help you schedule defragmentation (and a method for each drive separately) in the background.

A little inconvenient is that you need administrator-level access rights to run the program. Unfortunately, the official site does not support Russian or Ukrainian language for the interface and/or help system. A small disadvantage is the fact that when O O Defrag Professional is open and a new media is connected to the computer, such as a flash drive, this media is not displayed in the program. To add it to O O Defrag Professional, you have to restart the program.

As you can see from the review, O O Defrag Professional edition 14.5.543 x64 has a lot of options for defragmentation. The developers have taken care of the owners of laptops, and the owners of "strong" workstations and servers, and users of "office" computers. System administrators will find the jobs feature in O O Defrag useful. When installing O O Defrag Professional 14.5.543 x64, it offers to install a proprietary screen saver into the system, add a defragmentation call to the Explorer context menu (to defragment a specific file at the user's request) and install O O Defrag Professional edition as the default defragmenter in the system. Also, O O Defrag Professional has the ability to check for version updates from the developer's site.

O&O Defrag Free Edition- one of the most advanced utilities, primarily designed to defragment computer hard drives. The tool is quite powerful, however, its capabilities are not limited to this, especially if you also take into account compilation. And defragmentation tools are of particular interest.

Key Features of O&O Defrag Free Edition

First of all, you should pay attention to the defragmentation process itself. Standard tools of operating systems of the Windows family simply do not provide complete ordering of files and directories. In this case, we are dealing with a completely different technology that allows the application to work in two main modes.

On the one hand, this can be the usual ordering of files, and on the other, the optimization of free space on the hard drive. Let us immediately clarify that the usual ordering of the files of the most frequently used programs comes down only to the fact that they are overwritten in the fastest areas of the hard disk, from which, in the first place, the actual reading is performed.

In the second variant, the program is able to work simultaneously in the defragmenter and optimizer modes. In this case, not only the files are moved, but the use of the disk space itself is also improved. It is this combination that gives the greatest increase in the speed of the operating system as a whole.

By the way, in this way, you can fundamentally achieve the merging of some files into a single-type array. And this in no way affects their placement. Moreover, such ordering leads to the fastest access, for example, to files of the same extension such as graphics, music or office documents. It goes without saying that programs associated with such formats also run much faster.

In general, this software product shows itself quite worthy among the many competing programs. A particularly interesting solution, as mentioned above, is the dual mode of operation. And by the way, it is fully automated. The user does not need to go into advanced settings to configure all this. It is enough to select the mode itself in the main application window. This software will do the rest for you. And the interface itself is very simple and intuitive. To some extent, many tend to say that such an interface with its simple design attracts most users, even those who have never encountered this type of software product at all.

Spreading: shareware O&O Defrag - handy defragmenter with wide functionality. The program supports FAT, FAT32, NTFS and EFS file systems, can work with large volumes up to several terabytes, and stands out with two unique technologies. Thanks to ActivityGuard technology, the utility monitors the activity of the computer and ensures that the defragmentation process is carried out in the background without being noticed, reducing or increasing its activity in a timely manner. And support for OneButtonDefrag technology allows you to fully automate the defragmentation process and carry it out in accordance with user-defined settings when a certain level of fragmentation is fixed on the disk. Defragmentation can be performed on demand or automatically - according to a schedule or when the computer is inactive ("Screen Saver Mode"). The program works even with fairly small amounts of free space (5%) and allows you to run the defragmentation process not only for one, but also for several or even all disks installed on the computer. There is also selective defragmentation of files and folders, however, it is implemented in a way that is not quite usual for defragmenters - through the explorer context menu. But it does not provide for the consolidation of free space into a single area. In addition, O&O Defrag may have problems processing individual files if the program cannot find a free disk area of ​​sufficient size - in this case, the utility, having fixed a certain percentage of the work done, for a long time (if not forever) "thinks about life", and the process often has to be removed. After that, you can make the program work again only by manually starting the O&O Defrag service. So, in our opinion, not everything is perfect in the algorithm of this program. At the same time, in fairness, it should still be noted that if the named problem is not observed on a particular disk, then the program does its job perfectly. The demo version of the program (there is no Russian-language localization) is fully functional and operational for 30 days. The commercial version costs $49.95. In practice, using O&O Defrag is easy. The program window has four tabs - the "Defragmentation" tab combines tools for analyzing and defragmenting disks. The "Jobs and Reports" tab provides management of reports on the work done, the "View" tab provides access to information about the disk and files (disk map, disk status, etc.). ), you can download updates and view help information from the "Help" tab. Analysis of selected disks is launched by clicking on the "Analysis" button or by selecting the "Analyze" command from the context menu. Based on the results, detailed statistics are provided in several versions: in the form of a disk map showing empty space, an MFT area, defragmented files, etc. (by clicking on any block, you can see all the files it contains) and a disk status pie chart indicating the level its fragmentation. The program provides five defragmentation methods that differ in optimization strategies: Stealth, Space, Complete/Access, Complete/Modified and Complete/Name. The first two methods allow you to achieve results in the shortest possible time, but are less effective. These methods are recommended for initial defragmentation of never-before-defragmented drives. If you select the Stealth method, the program tries to optimize the available free disk space, while not all files are defragmented, and no optimization of their placement is provided. The developers recommend using this method to defragment disks with a very large number of files (more than 500,000) and/or with very little free space (5%). The Space method aims to increase the size of contiguous free areas and ensures defragmentation of all files, but can only work if there is a large enough free disk space and a relatively small number of files; recommended for background defragmentation. Even more free disk space is required in the Complete/Access, Complete/Modified and Complete/Name methods, which provide a complete defragmentation of all available files (including large and system files, as well as the MFT area) with optimization of their placement. The difference between these methods is in the optimization strategies. Thus, with the Complete/Modified method, files are located taking into account their modification, which is effective on disks where some files, in particular, databases, are regularly modified. And when you select the Complete/Name method, the files are sorted in alphabetical order - this is useful for quickly launching system libraries on disks where files are rarely modified. Defragmentation of one or several selected disks is started by selecting the desired defragmentation method from the context menu (or by pressing certain keyboard shortcuts) or immediately for all disks installed on the computer by clicking on the "Defragment Computer" button (in the latter case, the Space method is used automatically).

To speed up the defragmentation process, analysis and movement of individual files can be excluded - such files are specified directly in the program settings ("Settings" button, "General" tab).

Offline defragmentation is also provided (defragmentation before the OS starts, which allows you to defragment locked system files) - this mode is enabled in the program settings ("Settings" button, "Offline Defragmentation" tab).

Paragon Total Defrag 2009

Developer: Paragon Software Group
Distribution size: 17.4 MB
Spreading: Shareware Paragon Total Defrag is a defragmenter offered both standalone (only in the English edition) and as part of Partition Manager and Home Expert solutions. The first of these solutions is positioned as a universal tool for working with partitions and data on hard drives and allows you to perform any standard operations with partitions, as well as a number of other actions, including disk defragmentation. The second solution is a hard disk maintenance software package that can solve almost any problem that may arise during the operation of a hard disk, quickly and with only minimal computer experience. Both solutions have Russian-language localizations and are offered to Russian users at more attractive prices (490 rubles and 690 rubles, respectively), so purchasing Paragon Total Defrag as part of them is more reasonable. Paragon Total Defrag is a powerful and efficient defragmenter, yet relatively easy to use. It supports FAT16 / 32, NTFS, Linux Ext2 / 3 and Linux ReiserFS file systems and, unlike most similar solutions (and in this article, unlike all other utilities), it can perform not only background, but also full low-level defragmentation systems. As a result, an almost zero level of fragmentation is provided, and the files are placed taking into account the optimization strategy. This process is carried out in the mode of exclusive access (with restarting the computer) to the partition and turns out to be quite lengthy - at the same time, there can be no question of any possibility of access to the computer for this period. During defragmentation, all files are processed, including large (even more than 128 GB) and system files, as well as the MFT area, and the contents of temporary files can be ignored. It is possible to rewrite the MFT in a more compact way (MFT compression), which also improves the speed of accessing files on NTFS partitions. Defragmentation is performed with a minimum amount of free disk space (1%), and with such a minimum of free space, not many defragmenters can work. But it is impossible to use Paragon Total Defrag for any kind of selective defragmentation (defragmentation of folders and files or free space), since nothing of the kind is provided in this utility. There are also no automation options, which, however, is quite logical, since running low-level defragmentation on the machine is at least unreasonable. The demo version of the program is functional for 30 days, but has limited functionality - some of the operations in it work only in virtual mode. The cost of the commercial version is $29.95. By default, the program window has three panels - two basic horizontal and one additional vertical, which is easy to disable through the command menu. The horizontal panels display disks and operations with them (the top of the panels also has access to help), and the vertical one contains tabs with help information. The technology of working with Paragon Total Defrag is, in general, simple. First, in the "Disk Map" disk map, you should select the desired disk, and then start the operation of interest - that is, disk analysis or defragmentation, and then patiently wait for the end of the process. True, there are some nuances here - the program performs a preliminary disk analysis immediately after selecting it in the disk map, however, for a more detailed analysis, you will have to use the Partition > Defragment > "Analyze Fragmentation" command. If the disk is not bootable, then the program will carry out such an analysis and display the results without rebooting the system, otherwise you cannot do without it. In addition to disk analysis, you can also test its surface (Partition > "Test Surface"). As for defragmentation (the "Defragment Partition" button or the Partition > Defragment > "Defragment Partition…" command), there are two modes for its implementation - fast (Fast mode) and slow (Safe mode), which are selected through the program settings (Tools > settings). By default, "fast defragmentation" (Fast mode) is launched for the selected partition, however, if in the current operating system (say, the system partition is selected), the program cannot get the access to the partition it requires, then it will offer to restart the computer in a special mode. Before rebooting, you will need to define the settings for the operation, in the list of which you can refuse to save the contents of the Pagefile.sys and/or Hiberfile.sys files and set the desired data sorting option (sort files according to their size or the time they were last updated).

In "Fast mode" access to the computer is not blocked, and the operation is relatively fast and can be stopped if necessary. But when defragmenting in this mode, a power outage, hardware failure, or system failure can lead to data loss (this is a problem with all defragmenters). If the "Safe mode" is set, such a sad outcome of events is completely excluded, since a copy will be created for each file beforehand. True, this will take a lot of time, and there can be no talk of any activity on the computer during the defragmentation period, so it is wiser to start the process at night. Interrupting the process and restarting the computer during defragmentation in this mode is completely unacceptable. But everything will be reliable, and the results of defragmentation will be better, since the program will be able to access all the files. For comparison, we recall that when defragmenting in the background (that is, through the API), some part of the files (that is, those files that the program could not access) always remain fragmented.

O&O Defrag Pro 23.0 – one of the most famous and high-quality programs for defragmenting hard drives of personal computers. The program quickly eliminates fragmentation of files and arranges them in the right order. O&O Defrag Professional offers a huge selection of new and unique features that allow you to effortlessly optimize the performance of your system.

To create a new schedule, according to which the defragmentation will be performed, and configure all its parameters, just a few clicks of the mouse. With support for the new OneButtonDefrag technology, the program is able to automatically configure settings and adapt to the specific requirements of your system. Especially for users of mobile devices, IntelligentPowerControl technology is designed, which puts the hard disk defragmentation process into standby mode when the laptop is disconnected from the mains, thereby increasing battery life. When you connect your mobile computer to the electrical network, defragmentation automatically resumes. Thanks to this product, hard drive analysis and defragmentation is much faster and more efficient than ever before. Hard disk performance will increase by 5-8 times, even if you thought it was impossible! You can download the program via a direct link (from the cloud) at the bottom of the page.
