Good day!

Despite the fact that Windows has a built-in disk defragmenter, there are hundreds (if not more) analog programs (which do it ten times better!).

The fact is that, in my opinion, Microsoft added it to Windows so that it was, and its work is far from ideal (work algorithms are imperfect, there is no detailed schedule and settings, you cannot manually specify specific folders and files, etc.) ...

Addition!

If you don't know what defragmentation is and how to perform it, I recommend that you check out this help article:

Best utilities for defragmenting HDD

❶

IObit Smart Defrag

A very powerful disk defragmenter that, thanks to its unique algorithms, is able to maximize the performance of your disk subsystem!

The program not only defragments the files themselves, but also distributes them on the disk in a special way: according to how often they are used. All operations can be configured to be performed in automatic mode(which means you will not be distracted and waste time on optimizing the system every time).

That's all.

For additions on the topic - a separate merci!

This is a process during which the location of files on disk is optimized. This optimization allows you to increase the speed of working with files, and therefore improve the performance of your computer as a whole. In this article, we will talk about how to defragment a disk using the tools built into Windows, as well as using strony programs.

Defragmentation tips:

• Do not defragment drives. For SSD drives defragmentation is an absolutely useless action. It only reduces the resource of the SSD drive, while it does not give any gain in operating speed.
• Free disk space is required to perform defragmentation. The more free space, the faster and better the disk defragmentation will be performed. The minimum amount of available space is 15 percent of the total disk space.
• If you want to get stable high speed work, then use scheduled defragmentation.
• Try not to use the disk that you are defragmenting.

How to defragment a disk using Windows

The Windows operating system has a built-in mechanism for defragmenting disks. To use it, open "My Computer" and call the properties of the section that you want to fragment.

In the window that opens, go to the "Service" tab and click on the "Run defragmentation" button.

After that, the "Disk Defragmenter" window will open in front of you. Here you need to select the disk that you want to fragment and click on the "Analyze disk" button.

After the analysis of the selected disk is completed, you will see the value of the percentage of fragmented data on the disk. If this percentage is significant, then you need to defragment. For example, I analyzed disk "E" and the percentage of fragmented data on it is zero. You do not need to defragment this disk. But after analyzing the "C" drive, it turned out that it is fragmented by 36 percent, which means it needs to be defragmented.

In order to defragment the "C" drive, select it in the list of drives and click on the "Disk defragmentation" button.

After that, the defragmentation process will begin. The time it takes to defragment a disk depends on the amount of defragmented data and the speed of the disk itself. This usually takes at least a few hours.

In addition to manually launching defragmentation, you can use scheduled launch. To do this, in the Disk Defragmenter window, click the Enable Schedule button.

After that, you will see a small window "Disk Defragmenter: Change Schedule". Here you need to enable the function "Run on schedule" and configure the schedule.

Defragmentation can be performed daily, weekly, and monthly. After setting up the schedule, close all windows by clicking on the "OK" button.

Defragmenting a disk using third-party programs

You can also defragment your disk using third-party programs... Now there are many high-quality ones. Of the free, the most popular are Piriform Defragger, Auslogics Disk Defrag, MyDefrag, IObit Smart Defrag. There are much more paid programs, the most famous of them are: O&O Defrag, Ashampoo Magical Defrag, Raxco PerfectDisk, Auslogics Disk Defrag Professional.

For example, consider the process of defragmenting a disk using the free program Auslogics Disk Defrag Free.

After starting the program, check the boxes against the disks you want to defragment and start analyzing them.

After analysis, the program showed that the C drive was 46 percent fragmented. In order to defragment this disk, set the checkbox and click on the "Defrag" button.

This is all that needs to be done, it remains only to wait for the end of the defragmentation process.

Like a built-in defragmentation utility, Auslogics Disk Defrag Free allows you to defragment your disks on a schedule. To do this, open the "Setings" menu and select the "Scheduler" item.

This will open a window with a defragmentation schedule. Here you need to enable the "Defragment automaticaly" function, select the defragmentation time and disks.

After that, Auslogics Disk Defrag Free will defragment automatically at the specified time.

Devices for recording information need so-called optimization. First of all, this concerns the computer's hard drive, which can contain a huge amount of content. In windows xp, the procedure for optimizing the hard drive is based on 3 whales: enabling dma mode, caching disk writes and defragmentation.

If the first two parameters are already configured in the system by default, then the last one always raises the question of how to defragment. Since it is she who requires periodic intervention from the user.

Process description

Before considering how to do defragmentation, let's describe the process of this procedure itself. Then we will look at the utilities built into xp and the auslogics software package, which also has a separate defragmenter application.

So, the above procedure has the following features. When the user starts, he assumes the result - acceleration of working with the computer and starting everyday tasks.

On the hard disk, data are recorded in small portions by sectors. The entire file or folder with files fits within one sector. But over time, with the constant addition of new content to the HDD, these very objects are displaced relative to the primary position in such a way that one part of a file or folder may be in the initial sector, and the rest in other non-contiguous sectors. This creates scattered pieces of content that take longer than usual to access.

Thus, in order to speed up reading data from disk and, therefore, reduce the time to open an application or document, you need to combine these fragments. We will now look at how to do it using the example of a standard windows xp utility - the defrag.exe program

This utility has and you can call it through the working system management console - MMC. There are two ways to launch this console.

1. In the "start" menu, open the "run" item, then enter mmc into the working command window, but I recommend doing it more wisely.
2. Namely: right-click (touchpad) on the "computer" icon and select the "computer control" option.
3. The windows management console will open, divided into two parts. In the one that is smaller and located to the left, we will finally see how to do defragmentation.
4. Select the item "disk defragmentation" and click on it. A window will open in which you can perform this procedure on specific partitions of the hard drive.
5. Suppose we need to find out if there are additional fragments on the system partition FROM... Select the icon of this section with a mouse click and press "disk analysis". The program will analyze the current state of the partition and display a detailed summary of whether defragmentation is needed for the selected volume.
6. If the disk needs processing, press the "defragmentation" button and wait for the result. After completing the procedure, the application will display a report on the work done. If some files could not be optimized, it is possible that there is not enough free space on the partition. Then, before defragmenting, free up additional space and then try again.

We use for optimizationauslogics 5

The above set of programs is designed for windows optimization... Also included in the auslogics series 5 is a defragmenter. Here's how to defragment using it (it is assumed that this complex is already installed):

1. Launch the application using the shortcut on the windows desktop.
2. Click on the blue ball icon in the tray (near the clock).
3. With the right mouse button, sequentially use the list of submenu "Tools" - "Disk maintenance / defragmentation".
4. In the program window that opens, analyze or defragment the partitions. The utility from auslogics has advanced features when compared to the built-in system optimizer. Otherwise, its functionality is similar to the defrag.exe interface.

Good hour!

If you want it or not, but for the computer to work faster, you need to carry out preventive measures from time to time (clean it of temporary and junk files, defragment it).

In general, I can download that most users very rarely carry out defragmentation, and in general, do not pay due attention to it (either out of ignorance, or simply out of laziness) ...

Meanwhile, doing it regularly - you can not only speed up your computer a little, but also increase the life of the disk! Since there are always a lot of questions regarding defragmentation, in this article I will try to collect all the main things that I myself encounter quite often. So...

FAQ. Defragmentation questions: why, how often, etc.

1) What is defragmentation, what is the process? Why do it?

All files on your disk, while writing to it, are written sequentially in chunks to its surface, they are often called clusters (this word, probably, many have already heard). So, bye HDD empty, then the clusters of the file may be nearby, but when the information becomes more and more, the scatter of these pieces of one file also grows.

Because of this, when accessing such a file, your disk has to spend more time reading information. By the way, this scatter of pieces is called fragmentation.

Defragmentation it is aimed precisely at bringing these pieces together compactly in one place. As a result, the speed of your disk and, accordingly, the computer as a whole increases. If you haven't defragmented for a long time, this may affect the performance of your PC, for example, when you open some files, folders, it will start to "think" for a while ...

2) How often should you defragment your disk?

Quite a common question, but it is difficult to give an unambiguous answer. It all depends on how often your computer is used, how it is used, what disks are used on it, what file system. In Windows 7 (and higher), by the way, there is a good analyzer that will tell you what to do defragmentation, or not (there are also separate special utilities that can analyze and inform you in time that it's time ... But about such utilities - below in the article).

To do this, go to the control panel, enter "defragmentation" in the search box, and Windows will find the link you need (see the screen below).

3) Do I need to defragment SSD solid state drives?

Not necessary! And even Windows itself (at least new windows 10, in Windows 7 - it can be done) disables the analysis and defragmentation button for such disks.

The fact is that an SSD drive has a limited number of write cycles. This means that with each defragmentation, you reduce the life of your disk. Moreover, in SSD drives there is no mechanics, and after defragmentation, you will not notice any increase in the speed of work.

4) Do I need to defragment a disk if it has an NTFS file system?

In fact, it is believed that the NTFS file system needs little or no defragmentation. This is not entirely true, although it is partly true. It's just that this file system is designed in such a way that you need to defragment the hard disk under its control much less often.

In addition, the speed of work does not drop so much from strong fragmentation, as if it were on FAT (FAT 32).

5) Do I need to clean the disk from "junk" files before defragmentation?

It is highly advisable to do this. Moreover, not only to clean from "garbage" (temporary files, browser cache, etc.), but also from unnecessary files (movies, games, programs, etc.).

If you clean up the disk before defragmenting, then:

• speed up the process itself (after all, you will have to work with fewer files, which means the process will end earlier);
• make Windows work faster.

6) How to defragment the disk?

It is advisable (but not necessary!) To install a separate special. a utility that will handle this process (about such utilities below in the article)... Firstly, it will do it faster than the built-in Windows utility, and secondly, some utilities can perform defragmentation in automatic mode without distracting you from your work. (for example, you started watching a movie, the utility, without interfering with you, defragmented the disk at this time).

But, in principle, even a standard program built into Windows does defragmentation quite efficiently (although it does not have some of the "goodies" that third-party developers have).

7) Should defragmentation be done not on the system disk (i.e. on the one on which Windows is not installed)?

Good question! It all depends again on how you use this disk. If you only store movies and music on it, then there is little point in defragmenting it.

It's another matter if you install, say, games on this disk - and during the game, some files are loaded. In this case, the game may even start to slow down if the disk does not have time to respond to it. As it follows, with this option - defragmentation on such a disk is desirable!

How to defragment your disk - step by step

By the way, there is universal programs(I would call them "harvesters"), which can perform complex actions to clean up your PC from junk, delete erroneous registry entries, configure your Windows OS and defragment (for maximum speed!).

1) Cleaning the disk from garbage

For example, I can recommend Ccleaner... Firstly, it is free, and secondly, it is very easy to use and there is nothing superfluous in it. All that is required from the user is to click the analysis button, and then clear the disk from the found garbage (screen below).

2) Removing unnecessary files and programs

At worst, you can use the standard utility built into Windows (to open it, use the control panel, see the screenshot below).

3) Start defragmentation

Consider launching the Windows built-in disk defragmenter (since it eats me by default on everyone who has Windows).

First you need to open the control panel, then the system and security section. Further, next to the "Administration" tab there will be a link "Defragmentation and optimization of your disks" - go to it (see the screen below).

An alternative way to run defragmentation in Windows

1. Open "My Computer" (or "This Computer").

3. Then in the properties of the disk, open the "Service" section.

4. In the service section, click the "Optimize disk" button (everything is illustrated in the screenshot below).

Important! The defragmentation process can take quite a long time (depending on the size of your disk and how fragmented it is). At this time, it is better not to touch the computer, not to run resource-intensive tasks: games, video encoding, etc.

The best programs and utilities to defragment your disk

Note! This subsection of the article will not tell you all the features of the programs presented here. Here I will focus on the most interesting and convenient utilities (in my opinion) and describe their main differences, why I chose them and why I recommend trying ...

1) Defraggler

Simple, free, fast and easy to use disk defragmenter. The program supports all new versions of Windows (32/64 bit), can work both with entire disk partitions and with individual files, supports all popular file systems (including NTFS and FAT 32).

By the way, about defragmenting individual files is, in general, a unique thing! Not many programs can allow you to defragment something specific ...

2) Ashampoo Magical Defrag

To be honest, I like the products from Ashampoo- and this utility is no exception. Its main difference from similar ones of its kind is that it can defragment the disk in the background (when the computer is not busy with resource-intensive tasks, which means that the program does not hinder or hinder the user in any way).

That is called - once installed and forgot this problem! In general, I recommend paying attention to it to everyone who is tired of remembering defragmentation and doing it manually ...

3) Auslogics Disk Defrag

This program can transfer system files (which need to provide the best performance) to the fastest part of the disk, thereby slightly speeding up your Windows operating system. In addition, this program is free (for regular home use) and can be configured to automatic start during PC downtime (i.e. by analogy with the previous utility).

I also want to note that the program allows you to defragment not only a specific disk, but also separate files and folders on it.

The program is supported by all new Windows OS: 7, 8, 10 (32/64 bits).

This is one of the fastest disk defragmenters! Moreover, this does not affect the quality of defragmentation. Apparently, the developers of the program managed to find some unique algorithms. In addition, the utility is completely free for home use.

It is also worth noting that the program is very careful with data, even if during defragmentation any system error, a power outage or something else ... - then nothing should happen to your files, they will be read and opened in the same way. The only thing is, you have to start the defragmentation process again.

The utility also provides two operating modes: automatic (very convenient - set it up once and forget it) and manual.

It is also worth noting that the program is optimized to work in Windows 7, 8, 10. I recommend to use!

Defragmenters allow you to rearrange parts of files on your hard drive so that the fragments of the same file are sequential. This allows the hard drive to read and write information faster.

In other words, defragmenting makes reading a file faster because the hard drive does not have to move the read head to do so. The disk controller software will allow you to read the entire file in one go, which will significantly increase the speed of the disk subsystem.
It should be noted that defragmentation and defragmentation software are only useful for systems with hard drives. In the case of using SSD drives, no head movements occur and the controller of such a drive itself takes care of the placement of data blocks without requiring external intervention.

Although each of the Windows operating systems are equipped with own program for defragmenting hard drives, the use of third-party free software is fully justified, as it allows you to perform this process better and faster.

Note: only freeware programs are presented here, which are usually enough to perform a good defragmentation. Links to programs can be found at the bottom of the article.

Screenshot of Defraggler v2.20.989 on Windows 8

One of the best free software for defragmentation. It can be either in a version for installation on a hard drive, or in portable version... To reduce the operating time, you can set optimization not only for the entire disk, but also for individual folders.

Defraggler can start when the computer boots, check the disk for errors, empty the Recycle Bin before starting its work, exclude predefined files from the defragmentation process, select rarely used files and move them to the end of the disk to leave it at the beginning of the files that are used often.

The Piriform company that released the program is also known to users for its other popular products - CCleaner (system cleaning) and Recuva (data recovery).

Defraggler can be installed on Windows 10, Windows 8, 7, Vista, XP operating systems, as well as on Windows server operating systems.

Screenshot of Smart program Defrag version 5 on Windows

The freeware is great for the purpose of automatically optimizing files on a schedule. Automatic defragmentation settings even in free version are in many ways superior to many competitors.

The program allows you to start the movement of hard disk blocks during computer boot, thus gaining access to system or fixed blocks during normal Windows work files.

In addition, Smart Defrag allows you to exclude individual files or folders on a disk from the defragmentation process, replace the standard application of the Windows operating system, optimize only Windows Metro interface applications, and skip files that are of one size or another.

In addition, in the settings, you can set the preliminary deletion of unused and temporary files of the operating system and Internet browser Explorer to free the disk. Cached data is removed to speed up the process and exclude unnecessary and temporary data from it.

The program can be installed on computers running Windows 10, 8, 7, Vista, XP.

Screenshot of Auslogics Disk Defrag version 6 on Windows 7

Auslogic's Disk Defragmenter comes in two flavors: an installation version and a portable version for distribution on removable media.

The settings allow you to transfer the Windows system files and program libraries, as the most frequently used data, to the areas of the disk that are read the fastest. This setting improves overall computer performance by reducing system response times.

Like many other software, Auslogics Disk Defrag allows you to start the process at boot time. In addition, the hard disk can be checked with chkdsk for errors, it can be optimized, folders and directories can be added or excluded from the process, background checks can be run, temporary files can be deleted before starting defragmentation.

The Auslogics Disk Defrag program, even in its free version, works on almost all custom operating systems - Windows 10, Windows 8 and earlier.

Puran Defrag has its own data optimization engine - Puran Intelligent Optimizer (PIOZR). This engine, according to the manufacturer, intelligently moves files in such a way that they are located as much as possible on the outer areas of hard drives. At the same time, at the same speed of rotation of the disk spindle, the head manages to travel a greater distance per unit of time and, having read more data, ensures high speed of the computer.

Like many other programs on this list, Puran Defrag can defragment files and directories by right-clicking the context menu in the Explorer window. It can remove various temporary data before optimization to speed up the optimization process, it can work at boot time to access those files that are not normally available.

In addition, the software has some specific settings and capabilities. So its work can be started on a schedule by setting the number of hours of system downtime, after which you need to turn on, you can program disk defragmentation during the startup of the Screen Saver (screensaver).

In addition, you can start the process, for example, the first time the computer is turned on for the current day, or the first time the machine is turned on in a week or a month.

Along with the indisputable advantages, the program has disadvantages. So many researchers note that Puran Defrag tries to install a number of third-party programs during its installation.

Puran Defrag is compatible with many operating systems. And it can run Windows 10, 8, 7 and earlier.

Screenshot of Disk Speedup by © Glarysoft.com

Disk Speedup is another free hard disk defragmentation program that can work not only with an entire volume, but also with individual files and directories on it. You can start the file optimization process after a specified number of minutes of system inactivity has passed.

The software has some specific settings. This way you can exclude from processing files with fragments of less than 10 megabytes, files consisting of more than 3 fragments that have a size of more than 150 megabytes. All these values ​​are configurable.

In addition, large, rarely used files, files of certain formats (for example, video, graphics, archives, etc.) can be sent to the end of the disc, thus leaving small and frequently used data at the beginning of the disc. Thus, you can expect that the HDD head will not have to jump too often from one area of ​​the disk to another in its normal operation, which will lead to an increase in the speed of the system as a whole.

Among other things, Disk Speedup can be launched during system boot, can exclude individual folders and files from processing, automatically shutdown the computer when the process is completed on one or more disks, and run according to a set schedule.

Note: Disk Speedup tries to install some other programs of the manufacturer, however this behavior can be suppressed during installation by simply unchecking the corresponding checkboxes in the installer dialog.

The program is declared to work on computers running Windows 8, 7, Vista and others, including server computers. Independent testers tested the software on a computer running Windows 10 - everything worked without any complaints.

Free software from ToolWiz Software. It is characterized by a very fast installation process on a computer, a minimal interface. This software is said to be able to optimize the hard drive 10 times faster than the standard one. Windows tool... Knows how to move archives to a special slow part of the hard disk, providing small system files fast access.

The program shows the number of defragmented files on the disk, it really does its job very quickly, it can show the general level of fragmentation, it can schedule its launch at a later time.

While it is sometimes good to have a lightweight and simple tool for performing a function without being overwhelmed by unnecessary buttons or settings, sometimes they are very necessary. So Toolwiz Smart Defrag is designed in such a way that almost nothing can be configured in it. If the priority is to find the easiest to use, but effective and quick program- this is one of the best options.

Works under Windows 8 and below.

WinUtilities DiskDefrag is not a fully specialized program. This is an optimization system that includes, among other things, a module for disk defragmentation. It is, however, a fairly simple and highly customizable tool.

All the usual features for this class of free programs are also present here: work on a schedule, the ability to run while the system is idle, the ability to manage the computer's power.

In the settings, you can set more than 10 behaviors: only analysis, analysis and moving rarely used files to the end of the disk, etc. In addition, you can control the estimated optimization time, exclude folders and files.

Another feature of the software is the ability to select files and folders to move to a special area on the disk (SpaceHogs area), where the program tries to place large and rarely used objects. Therefore, in manual mode, you can flexibly configure the computer so that it works as quickly as possible.

In the settings, you can set the need for automatic shutdown of the computer upon completion of the defragmentation process.

The hard disk optimization module in the program can be found by selecting "Modules> Optimize & Improve> Disk Defrag" in the menu item.

The program works perfectly in the environments of the operating systems Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP.

Free version software O&O Software has a simple and well-designed user interface. Even in the free version, it contains most of the competitors' capabilities - disk optimization, viewing all fragmented disks, checking the disk for errors.

In addition to being able to run a scheduled scan and remediation on the desired day of the week, O&O Defrag Free Edition can be programmed to start when the screen saver starts.

For those who do not want to deal with the settings, there is an option to launch the settings assistant.

Some of the right opportunities are absent in the free version and are present only in the paid version. Therefore, it may happen that by turning on some option, the user will receive a message that in order to get this option, it is necessary to upgrade to a paid option.

Works under almost all common Windows operating systems. From Windows 10 to 8, 7, Vista. However, in reviews of this software, sometimes there are reports that it was not possible to fully launch it on a particular machine.

Screenshot of UltraDefrag version 7.0.0
