Brief description of WinRAR

The main activity of WinRAR is packaging files, groups of files and folders with attachments into RAR 4 and 5 archives, as well as ZIP, quickly and with strong compression. It is also important to unpack RAR, ARJ, 7Z, CAB, ISO, LZH, TAR, 7-ZIP, Z, ZIP files, regular and divided into parts, and formats of other popular archivers. It is possible to collapse self-extracting (SFX) and multi-volume archives of the required size, archives encrypted using the AES-256 algorithm with a password, excluding and including data in the archive, restoring damaged archives, checking for viruses and other malicious software. SFX archives can be equipped with a GUI and script-type commands for programming the unpacking process, for example, when installing programs or games. Additional information is used to reconstruct the archive. Such data will allow you to restore both a regular broken one and a multi-volume one in the absence of entire volumes. Additional information is also added to speed up unpacking. You will need to download WinRAR for free in order to work with a virtually unlimited number and size of files and a significant number of formats. The program downloads quickly and is easy to install, and can be integrated into the Windows Explorer context menu for accelerated access to basic functions and working with archives without launching the program.

Why it wouldn’t hurt to download an archiver for Windows

Sometimes you need to download a program, game, or e-book. Often they are compressed into an archive, which cannot be opened using standard means. This is especially true when a new Windows 7, 8.1 or 10 operating system has just been installed on your computer and is not yet fully equipped with software. In this case, the first thing you need to do after installing the Windows operating system is to download WinRAR for Windows 7, 8.1, 10. WinRAR will not take up much space on your computer and will quickly deploy any of the popular formats, even if the archive is damaged. If necessary, VinRAR will quickly and efficiently archive a file, several files or folders with files into an archive file RAR 4 or 5, or ZIP, and create a self-extracting SFX, multi-volume or password-protected archive. Advanced users also take advantage of other advanced functionality of the WinRAR archiver, which will be discussed below.

A brief history of the WinRAR archiver and the RAR format

WinRAR was created during the time of Windows 3.x, running on an operating system without a graphical shell, MS-DOS 3.1 or higher. The name is made up of the words Windows and Roshal ARchive. One letter is taken from the surname of the creator, Chelyabinsk resident Eugene Roshal. In addition to WinRAR, Evgeniy is the author of the popular file manager FAR Manager.

The RAR and UNRAR utilities for MS-DOS appeared at the end of 1993. In 2009, a more powerful 64-bit version of the program was released for Windows 64-bit with WinRAR 3.90. In 2011, from version 4.00, Windows 95, 98, ME and NT are not supported. In 2013, from version 5.00, the new RAR5 format is supported.

For those who use outdated versions that do not support the new RAR5 format, it will not hurt to download the latest version of VinRAR for free in Russian for Windows. The latest RAR5 has little in common with RAR4, although it uses the RAR extension. If you download the Russian version of WinRAR 5 for free, the archiver will be able to open and pack RAR4 and RAR5, but outdated ones do not understand RAR5. The fifth PAP allows you to comment on archives, but commenting on individual files is not available, there is no support for digital signatures, experimental technologies for text and multimedia compression. The dictionary size varies from 1 MB to 1 GB (for Win x32 - from 1 to 256 MB), 32 MB is preinstalled. Multi-volume files have file names name.partNN.rar, instead of name.rNN. Instead of the outdated AES-128, AES-256 is used. When monitoring integrity, a 256-bit BLAKE2sp hash, NTFS strict and symbolic links are used. The length of file names and paths has increased to 2048 characters for both RAR and ZIP. Added support for split 7Z, as well as ZIP and ZIPX with B ZIP 2, PP Md and L Z M A compression.

WinRAR interface

The WinRAR interface is designed in a classic style and will not raise any questions for most users who decide to download the WinRAR utility for Windows for free and install it on their computer, laptop, netbook or mobile phone. If questions still arise, you can refer to the built-in help. Some users prefer to use the built-in wizard assistant in step-by-step mode. The appearance of the interface can be changed by downloading and installing any theme (skin) you like. Support for about fifty language localizations, including Russian, allows you to work with archives in a software interface in your native language. The ability to download VinRAR for free in Russian on the page of this material on the site eliminates the need to translate menus, windows and settings. After downloading and installing the archiver on your computer, you can immediately start working, without spending time learning the capabilities and settings and translating the interface.

Here you can download the WinRAR archiver for free with the ability to integrate it into the operating system. Integration into Windows Explorer is convenient for those who do not want to waste time on routine operations. When you click the mouse in the Explorer window, a menu appears, using which you can collapse the archive or extract the contents to the current or specified folder. In the context menu, the following are available: automatic and manual unpacking and packaging, as well as packaging with sending by e-mail. Hotkey combinations allow you to speed up routine operations. Unfortunately, there are no scripts or macros for batch processing.

What's new in version: List of changes

In the Windows operating system, with default settings, extensions for registered file types are hidden. Therefore, there is often a need to find out what extension a file has.

Windows does not display registered file types; the user only sees the file name. These are most file types in the operating system.

In order to get information about what extension a given file has in Windows, you need to right-click on the file. In the context menu you need to select “Properties”. In the “Properties” window that opens, in the “General” tab, the user will see the file type.

The icons of some files in Windows can be similar to each other, so enabling the display of file types makes sense for two reasons: for convenience and for security purposes.

Many antivirus programs recommend displaying file extensions for greater security, since viruses can use icons of harmless files. The user sees a familiar file type, runs it, and this file has a completely different extension.

For example, files with the extension “.torrent” and “torrent.exe” are often found on the Internet. Externally, the icons are very similar. Therefore, after launching such a file, an inexperienced user risks downloading onto his computer something completely different from what he intended to download (movie, game, program, etc.). If file extensions were displayed on the system, it would be immediately obvious that a file with the “.exe” extension is masquerading as another file type.

You can enable the display of file extensions in the operating system using several methods: the first method is universal for Windows 7, Windows 8, Windows 8.1, Windows 10, the second method works separately in Windows 7 and separately in Windows 10, Windows 8.1, Windows 8.

How to show the extension of registered file types in Windows

Let's see how we can enable the display of file extensions in the Windows operating system in a universal way. All actions are similar in Windows 7 or Windows 8. In Windows 10, the procedure is no different, there is only a different name for the settings option.

Go to Control Panel (small icons view), select Folder Options. In Windows 10, in the “Control Panel” the setting is called “Explorer Options”, otherwise everything is the same.

In the Folder Options window, open the View tab. Uncheck the box next to “Hide extensions for known file types.” Then click on the "OK" button.

After this, file extensions of all types will be visible in the operating system Windows 7, Windows 8, Windows 8.1, Windows 10.

How to show file extensions in Windows 7

Another way in Windows 7 is to enter Folder Options from the Explorer window. Open Explorer, click on “Organize”, select “Folder and Search Options” from the context menu.

How to show file extensions in Windows 10 and Windows 8

In Windows 10 and Windows 8 operating systems, you can quickly access folder view settings from the Explorer window. In Explorer, go to the “View” tab, click on the “Options” button, and then on “Change folder and search options.”

In the Folder Options window, uncheck the box next to Hide extensions for known file types. To confirm the setting change, click on the “OK” button.

Now all files in Windows 10 or Windows 8.1 will have a visible file extension.

Conclusions of the article

The default settings in Windows hide extensions for registered file types. The user can enable the display of file extensions in the Windows operating system in several ways.

File Windows.edb is an index database of the Windows Search service (Windows Search), which provides users with a quick search for data on the file system by indexing files, letters in pst files and other content. Naturally, the more files there are on the system, the larger the size of the Windows.edb file can be. In some cases, it can grow to tens or even hundreds of GB, taking up all the free space on the system disk.

This file is and is stored by default in the directory C:\ProgramData\Microsoft\Search\Data\Applications\Windows\.

Note. This file is available in all modern MSFT client and server operating systems: from Windows 7/Vista/Server 2008 to Windows 10/Server 2016.

For example, in my case the size of the Windows.edb file is over 15.5 GB (which is almost 15% on my 100 GB SSD drive)

There are several ways to control the size growth of the Windows.edb file

Rebuilding the Windows Search index

The most “correct”, but not the most effective way to reduce the size of the Windows.edb file is to start the process of re-indexing data in the system. To do this, open Control Panel ->Indexing Options-> Advanced -> Rebuild(to open this dialog, just run the command rundll32.exe shell32.dll,Control_RunDLL srchadmin.dll).

After some time (usually quite a long time), the system will finish re-indexing the data and the size of the edb file will decrease slightly.

Defragment Windows.edb using Esentutl

Since the Windows Search index file is a database in EDB format, you can defragment it using a standard utility for maintaining such databases esentutl.exe— Extensible Storage Engine Utilities (should be familiar to administrators). Defragmentation of the database is performed offline (the database should not be in use), so you will have to stop the search services first. All these operations can be combined into one script:

sc config wsearch start=disabled
sc stop wsearch
esentutl.exe /d %AllUsersProfile%\Microsoft\Search\Data\Applications\Windows\Windows.edb
sc config wsearch start=delayed-auto
sc start wsearch

Advice. To perform defragmentation, there must be enough free space on the disk, because... a copy of the edb file will be created.

The esentutl utility displays the defragmentation progress on the screen while running.

Note. If you receive an error when running the esentutl command: Operation terminated with error -1213 (JET_errPageSizeMismatch, The database page size does not match the engine) after 10.125 seconds, this means that your system is 64-bit and to perform defragmentation you need to use the x64 version of esentutl. Those. the third command will look like this:
"C:\Windows\SysWOW64\esentutl.exe" /d %AllUsersProfile%\Microsoft\Search\Data\Applications\Windows\Windows.edb

In my case, the size of the edb file after defragmentation decreased by 30%.

Deleting and rebuilding the Windows.edb file

If your disk space is critically low, you can safely delete the Windows.edb file. To do this, stop the Windows Search service and delete the file.

net stop "Windows Search"
del %PROGRAMDATA%\Microsoft\Search\Data\Applications\Windows\Windows.edb
net start "Windows Search"

After restarting, the Windows Search service will begin the process of re-indexing the system and re-creating the Windows.edb file (system performance may decrease during the complete re-indexing process).

In some cases, when the size of the Windows.edb file is constantly increasing, it may make sense to move the Windows Search index base to another volume. Thus, extreme growth of the database will not lead to a system stop when free space on the system partition is exhausted. Typically, this needs to be done on RDS terminal servers where users actively work with files, personal folders, and other indexed content.

To change the file location openControlPanel\IndexingOptions\Advanced\Indexlocation->NewLocation and specify the path to the new location of the Windows.edb file.

Fix to prevent Windows.edb file from growing excessively in Windows 8/Windows Server 2012

To solve the problem of the constant increase in the size of the Windows.edb file in Windows 8 and Windows Server 2012, a special fix was released, which is included in the May 2013 update package - KB 2836988. It is recommended to download and install it on these versions of Windows.
