Choosing the optimal defragmenter for Windows: O&O Defrag - German pedantry? How to defragment your hard drive as efficiently as possible The most comprehensive view of the settings for all your drives

Improves system performance and also detects junk files occupying disk space with the integrated O&O DiskStat tool. The product is compatible with all modern versions of Windows.

The functionality of O&O Defrag 20 has been significantly expanded. The program can now detect more objects that slow down the system and are not affected by standard defragmentation. O&O Defrag 20 has a simplified and optimized user interface that allows you to perform various actions with ease. The new integrated DiskStat tool shows you exactly what your disk space is using. This information summary helps you identify and remove unnecessary files.

The new version has an improved high contrast mode to make it easier to recognize objects on the screen. Variable screen resolution is also possible when using O&O Defrag 20.

Even in the era of solid-state drives (SSDs), regular system maintenance and optimization is key. O&O Defrag 20 not only applies TRIM optimization, but also helps free up space with just a few clicks of the mouse, or automatically at a given time.

O&O Defrag 20 also optimizes virtual machines. The product defragments the virtual machine and files on the host system to ensure optimal performance of the virtual machine.

Thus, O&O Defrag 20 allows you to detect junk objects, temporary and unnecessary files and optimize hard disks and solid state drives.

New and improved features of O&O Defrag 20 Professional

Defragmentation methods STEALTH, SPACE and COMPLETE. STEALTH and SPACE are optimized for the most high speed defragmentation, and COMPLETE implies a more thorough defragmentation. The COMPLETE method requires more time and memory. Optimal use of current space also prevents further fragmentation. All methods can be applied to any disk, including storage, partitions and volumes distributed across array disks, and all guarantee maximum reliability.
O&O DiskCleaner. Search and delete temporary and unnecessary files, which use memory and increase fragmentation. O&O DiskCleaner improves data protection and system security because these files usually contain personal data (image thumbnails, document copies, email drafts, dumps).
. Limited storage capacity is becoming a problem for many modern laptops. O&O DiskStat offers quick review how it is used HDD. Users can easily find files and folders that are taking up valuable hard drive space and slowing down system performance. This universal tool has an interface in the style Windows Explorer and a wide range of possibilities for searching for garbage objects.

Improved SSD optimization . The file system on modern solid-state drives is very fragmented. O&O Defrag uses an SSD optimizer specifically designed to work with solid-state drives to eliminate and prevent fragmentation. The tool does not apply unnecessary recording operations and optimizes settings on a regular basis using the TRIM function. As a result, the performance and life cycle of the disk are extended - a process that the user cannot influence independently.
Data Security. IN latest version O&O Defrag removes unused disk space upon user request. This approach Helps prevent the unsafe deletion of sensitive content and temporary files that are in use by other users.
Supports vertical high contrast modes. The new version has received improvements to the high contrast mode, which makes it easier to recognize objects on the screen.
Variable Resolution. O&O Defrag optimally adapts to the selected screen resolution.
User interface. The O&O Defrag interface has been thoroughly redesigned to be more intuitive and easier to use.
Reduced defragmentation time. With O&O Defrag you can defragment multiple disks in parallel. Defragmentation algorithms have been optimized and accelerated, reducing the time required to complete an operation by 35 percent.
Automatic defragmentation. Automatic defragmentation is activated after installing O&O Defrag and allows you to defragment disks in background without reducing your computer's performance. Automatic defragmentation uses special procedures to monitor disk activity and ensure optimal use of system resources.
Optimizing virtual machines and storage networks. O&O Defrag optimizes the actual memory allocation for virtual machines and SANs. O&O Defrag is especially useful for virtual machine host systems due to the optimal distribution of virtual memory areas in the machine file.
Assessment and analysis. Every time you start the program, manual analysis of disks is available and the level of fragmentation of each media is shown. You can also display the most fragmented files, as well as the physical location of the fragmented files on your hard drive. During defragmentation, a dynamic block appears, and using the “before and after” view, the user can clearly evaluate the overall picture of system optimization.
Story. O&O Defrag provides clear graphic information about the actions performed and the results obtained.
Power management for laptops and netbooks. If the laptop or netbook is disconnected from external source power supply, the defragmentation process is interrupted so that the battery power is used for the user's basic needs.
Filling zones on disks. Logical separation of data into performance-critical and non-critical files is done using alternative setting, which allows you to split disks into so-called zones. Files are sorted based on frequency of use and placed in appropriate zones. For example, system files and frequently used programs are logically separated from other data, such as documents and downloads. Fragmentation is prevented using intelligent methods by separating infrequently and frequently used files. This logical layout not only reduces system boot times, but also prevents fragmentation of program files.
Automatic update . O&O Defrag automatically checks availability new version programs so that you can always use the latest defragmentation technologies.

The performance of the system as a whole is affected by many parameters. This and specifications equipment, and the number of running and running programs, and the volume hard drive and its performance. But the latter depends not only on the rotation speed of the plates. In many ways, the performance of the disk, and therefore the system as a whole, depends on how the files are placed on the disk. If files are written to the disk in consecutive sectors, then reading them will take less time than if they were written in chunks to various free disk spaces at the time of recording.

Statistics say that if the number of fragmentarily recorded files on a disk does not exceed thirty percent of their total number, then the operating conditions of the disk and its performance are close to optimal values. If up to half of the files are defragmented, the speed of working with the disk slows down. At a higher percentage, the disk begins to work under harsh conditions and takes longer to read files. The result is a noticeable slowdown in work.

There is, of course, a way out of this situation. And it consists of periodically checking the disk for fragmented files and optimizing their placement. To perform this work, programs are used different developers. One of them - O&O Defrag - is offered by O&O Software. The company offers two versions of the program - Professional Edition and Server Edition. The first option is designed to work on local computer and does not have a network management console, but can act as a client for a server solution. The server version has a program management console over the network. It can be used on both servers and workstations, which provides administrative control and monitoring of the defragmentation process on computers.

Modern Windows systems have own systems defragmentation, but while they are running it is extremely difficult to continue performing any tasks on computers. In this regard, the O&O Defrag program has a significant difference: its ActivityGuard component allows you to monitor the execution of tasks on your computer and take this into account when working. What is this? For example, if a screen saver is running on a computer, this means that other tasks on it are being performed to a lesser extent and, therefore, at this moment you can set a higher priority to the defragmenter's work or start a job that was suspended during high computer load. The component takes into account processor load and, when the processor load is low (for example, during a break from work), allocates more resources to the defragmentation process than at other times. ActivityGuard also takes into account the capabilities of laptops - when running on battery power, the program is suspended, which reduces power consumption.

When installing the program, you can choose to use it instead of the standard defragmenter. In this case, the program call is built into standard interface working with disks. In addition, during installation you can select the automatic disk defragmentation mode. The O&O OneButtonDefrag module monitors the status of disks and automatically runs a defragmentation program in the background if necessary. (This mode can be turned off and on again at any time.)

The program offers five defragmentation methods. Each of them provides efficient process file defragmentation, which allows you to continue working with other applications. The methods differ in the resources used and the principle of placing files on the disk during the defragmentation process. The least resource-intensive method is STEALTH. His distinctive feature there is a negligible requirement for memory used and additional disk space used for operation. This ensures the fastest defragmentation process. Recommended for use on file servers with big amount files, as well as with very large disk resources (more than one terabyte).

The SPACE method is very close to the previous one, but it better ensures file defragmentation and maximum reduction of free space into a single zone. This method is recommended for disks with a significant number of fragmented files. The method is less productive than the previous one. Therefore, it is recommended for processing disk arrays with a capacity of more than one hundred gigabytes or with a number of files of more than one hundred thousand (the previous method also works well with the number of files several times larger).

The following methods are a variation of their base type - COMPLETE, but differ in the principle of sorting files on disk. The method requires more resources than the previous ones, but ensures maximum system performance after defragmentation. The first type of method is to sort files by last access time. The most rarely used files are placed at the beginning of the disk, those that have been accessed recently are placed at the end. This reorganization of files allows you to spend significantly less time on defragmentation in the future, since the most “mobile” files will be located at the end of the disk. The method is recommended for use on servers where the best performance for data access is required.

The following method sorts by date last change files. Files that have been recently modified are placed at the end of the disk. The oldest ones go to the beginning. This strategy is recommended for defragmenting database servers. And finally - the COMPLETE method with sorting files by name. This method is most applicable for system drives and for drives that contain files that rarely change. It should be noted that three latest methods It is not recommended to mix with each other or with methods that do not perform structural reorganization file system. Having chosen one of them, you need to of this disk use it exactly.

A few notes about performing defragmentation. As noted, additional disk space is required to complete this process. And it should be larger, the larger the size of the files to be defragmented. You should also remember that you should try to avoid changing or moving files during defragmentation. O&O Defrag calculates the best positions for the files it moves before and during operation, and any change will affect these calculations. The consequence is an increase in the time to complete the operation due to additional recalculations.

If you install the option automatic execution defragmentation process, you can set a minimum response threshold (percentage of file defragmentation), below which the process will not start. Generally speaking, defragmenting disks on a regular basis is a significant factor in increasing performance. For this purpose, a task manager is built into the program. With its help, you can create an unlimited number of disk defragmentation tasks with individual settings for each of them. For each disk, you can set your own defragmentation time, select the required method, and the trigger threshold. In addition, the program has the ability automatic detection moment when you need to perform defragmentation. When you select this option, the program will determine the time of the next launch based on heuristic methods. The more fragmented the disk, the more often the program will run. If this condition is eliminated, the program will launch less frequently.

Defragmentation tasks can be quite precisely customized to suit your requirements. Thus, you can choose one of four levels of recording information in log files (differing in the level of detail). You can specify files that should not be defragmented. It is possible to check the disks before defragmentation begins. For partitions located on different media, you can set defragmentation to run in parallel. If the partitions are located on the same physical medium, they will always be processed sequentially, in alphabetical order.

The defragmentation process is running and not in automatic mode. In this case, the sequence of actions is specified by the user. First, the disk is analyzed (and before that, you can run the verification procedure). As a result, a report is generated that gives a detailed picture of the disk's condition. The report window has four tabs. The first one shows general information about the disk - total volume, data about the file system and the use of clusters. The second tab shows a list of defragmented files and the number of separate fragments for each. The third is a list of files that cannot be moved even if they are defragmented. The last tab shows the generalized results of disk analysis. The most curious users can also see which specific files occupy a particular cluster. To do this, use the main program window, which shows the clusters of the disk under study. To view, just select the cluster you are interested in and click on it with the mouse pointer. In the window that opens there will be full list files that ended up in this cluster.

In addition to the information that can be viewed through the program interface, you can generate an external report. It contains virtually all the same data, but it can be saved (it is generated as an html page), printed, or sent to someone.

In general, the program is very interesting and convenient. Possibility to launch from command line allows you to embed it in various scripts. And the network version is of particular interest to the system administrator.

“I have already touched on the topic of disk defragmentation. O O Defrag Professional is very effective and functional software for defragmentation hard drives, flash and solid state drives.

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

five defragmentation methods.
Complete defragmentation of the hard drive in almost any case.
Work with external USB drives.
32 and 64 bit support Windows versions 7, Vista, XP.
Convenient, intuitive interface.
Ability to obtain a large amount of disk information related to defragmentation.
Ability to run defragmentation according to plan.
The ability to perform parallel and sequential operations on disks.
Disk defragmentation at boot operating system.
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. Taking into account a large number of factors (drive type, file system, cluster size, size of stored files, operating system, frequency of disk use, and so on), hard disk defragmentation will have a different “usefulness”. Now (mid-2011) there is an active transition from storage drives to hard drives magnetic disk to solid state drives (SSD). Flash drives are the most popular devices for “transferring information in your pocket.” For hard magnetic 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-reducing role.” Many articles have already been written about this.

It is worth noting a specific area of the “hard drive” - Windows registry. To check and defragment it, I recommend the system utility TweakNow PowerPack.

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

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

50 MB of free disk space for installation.
Access right level Administrator.
Operating systems supported: 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 (picture below) can be divided into three areas.

Menu.
Disk table.
Disk information.

The menu area is visually divided into five groups.

Defragmentation.
Reports.
File system.
Options.

Region Disk table by default contains twelve columns.

Disk. Volume letter.
Name. Volume label.
Action. Displays the status of the action being performed on the disk.
Status. Percentage of action completed.
Total files.
Fragmented files.
Fragmentation percentage.
Size. Disk size.
Free. The amount of free disk space (in gigabytes).
File system.
Current file or folder. The full name of the file (folder) on which the action is currently being performed.
Time left. Time until the operation is completed.

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

To the region Disk information(picture below) defragmentation of the hard drive is presented in a visual form.

Contains five tabs.

Type of clusters.
Tasks. The tasks will be discussed in detail below in the article.
Reports.
Disk status.
File status.

Tab Type of clusters(picture above) contains a graphical representation of the disk file system and a color legend. If desired, you can change any of the legend colors. 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 progress.
Directories.

All of them display the ownership of a particular location on the disk to various types of files (or directories). You can customize the display of the graphical view using the following options.

Classic representation of clusters. Will remove the gradient from the clusters. Makes them one color.
Shadow. Adds or removes 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 various types files. Information about the contents of a specific colored cell can be found by double-clicking on it.

The figure above shows the display of cells in a non-classic form, 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 gradient of 3 pixels. I will also provide information about the contents of one such cell.

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

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

Tab Disk status(picture below) displays brief information about the selected disk.

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

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

Fragmented files.
Large fragmented files.
Fragmented system files.
Large system files.
Fragmented locked files.
Large locked files.
Large files.

You can sort any of the filtered lists in forward or reverse order by the following columns.

File name.
File size.
Fragments. Number of file fragments.
File fragmentation percentage.
Initial cluster. The number of the cluster on which the beginning of the file is located.

O O Defrag Professional has options that allow you 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 defragmentation and/or start executing it immediately.

You can specify automatic disk optimization (in the background), disk optimization during system downtime, or optimization time (day of week, hour, minute). You can specify the flag for 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.

Express.
Space.
Full/Name.
Full/Date of changes.
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 high-speed method uses a smaller volume (compared to other methods) random access memory. It gives good results even on computers with little RAM and little free disk space. The method consists of attempting 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, more than 4 terabytes).
Computers with a very large number of files (more 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 likelihood 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, more than 1 terabyte)
Computers with a large number of files (more than 100,000 files).

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

All types of servers and automated workstations.

Method Full/Date of Changes. A method that is more demanding on hardware resources and longer in execution time than Express and method Space. However, it provides a larger percentage of file system performance gains. In addition to defragmentation, it reorganizes the file structure. Files are sorted according to last modified date. Files that have not been recently modified will be placed at the beginning of the disk, and recently modified files will be placed 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 defragmentations to proceed as quickly as possible, since 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 a lot of free disk space.

Full/Access method. A method that is more demanding on hardware resources and longer in execution time than Express and method Space. However, it provides a larger percentage of file system performance gains. In addition to defragmentation, it reorganizes the file structure. Files are sorted by the date they were last accessed. Files that are rarely accessed are placed at the beginning of the section. Files that are accessed frequently are placed at the end. Rarely used files are defragmented and not moved in the future. This method allows future defragmentations to proceed as quickly as possible, since 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 a lot of free disk space.
All types of servers and workstations.

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

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

Main.
Schedule.
Disks.
Files.
Activity monitor.
Settings.
Steps to take before defragmentation.
Actions after defragmentation.

Let's look at these tabs in a little more detail.

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

Tab Schedule(picture below) You set a schedule for completing this task. You can select one-time execution (indicating the time and day), weekly (indicating the day/day of the week, period from/to and start time of the task) and execution of the task during the startup of the screen saver (assuming that you are not working at the computer).

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

On the tab Discs(picture below) it is possible to specify for each disk individually 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.

Excluded files. Files that do not need to be defragmented.
Files that need to be defragmented.
Files, by size. To reduce 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(picture below) allows you to configure system busy tracking for task execution. It is very comfortable! For example, you planned a complete defragmentation of all disks with a file system check before and after defragmentation. And they 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 the movie is saved big size. If you run the task despite the PC loading, 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 processor and hard drive load at which the task will not be launched. It is also possible to specify the name of the program, when active the task will also not be launched. You can specify that the task cannot be run 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 mode.

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

Consider removable media.
Consider 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 completing a task.

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

There you can delete, run and edit the task.

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 the disk into zones allows you to logically differentiate data into critical and non-critical. A special algorithm checks that after defragmentation the data on the disk is optimally organized. The placement of files in zones is also checked, depending on the settings. For example, system files that need to be accessed frequently and quickly are separated from other data, such as movies and music. This will reduce the percentage of file fragmentation, shorten 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 configured zones. 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.

Main.
Disk defragmentation at boot.
Automatic optimization.
Files. This tab is discussed in more detail above.
Activity monitor. This tab is discussed in more detail above.

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

Checking the disk for file system errors before defragmentation and canceling defragmentation if an error is detected.
Optimize multiple physical disks in parallel.
Optimization according to the characteristics of the disk file system.
Consider removable media.
Consider 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.

Boot defragmentation. On this tab (picture below) you can set disk defragmentation when loading the operating system (at each boot, only at the next boot).

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

A little inconvenient is that to run the program you need administrator level access rights. Unfortunately, the official website does not support Russian or Ukrainian languages 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, for example 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 large number of capabilities for performing defragmentation. The developers were concerned about the owners of laptops, and about the owners of “strong” workstations and servers, and about the users of “office” computers. For system administrators will useful function tasks in O O Defrag. 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 context menu Explorer (for defragmentation specific file at the user's request) and install O O Defrag Professional edition as the default defragmentation program on the system. O O Defrag Professional also has the ability to check for version updates from the developer’s website.

In the last article on this site, I told you about what defragmentation of a computer disk is, why it is needed, how often it needs to be done, and mentioned the programs with which you can do it. Today I’ll tell you in detail about one of these free programs, which, in my opinion, copes better with defragmentation than others. hard HDDs disks - O&O Defrag Free.

We're talking about a free program called . Download links on the official website of the authors of the program free version not anymore. Apparently the free version is no longer supported by them. Therefore, here is the free version from this site. You can also find this program on the Internet by Googling. I have a version O&O Defrag Free 14.1.431. The program does not support the Russian language, but in this article I will tell you and show you clearly how to carry out defragmentation and you will not have any difficulties with it. For those who still want to get to know the program very closely, there is also a crack in the archive. The translation was made by enthusiasts for the professional version of the utility, so I can’t say anything about the accuracy of the translation.

What's good about this program?

The main advantage of the program is defragmentation quality. It's top notch. The algorithms used in the utility are very effective, which immediately has a beneficial effect on optimizing the operation of the computer. Thus, programs start noticeably faster, some program lags disappear, system loading/rebooting is done many times faster, and so on. And this free program for defragmentation.
I tested several of its other paid analogues, and when I checked the disks again, they confirmed that I did everything very well.

Program installation and configuration
