One of the most important programs, in my opinion, is a program that allows you to archive and unarchive files. Especially for a novice PC user, of these two options, most of them need to be unzipped. And in this post we will look at free archiver 7-Zip.
Archivers allow you to compress data so that it takes up less space on your computer. And especially now, archivers are used if you need to transfer any files over the Internet, in order to reduce the size or weight of the transferred files as much as possible.
Typically, files packed by archivers have a designation (extension) that looks like this at the end of the file name: .rar or .zip.
So, if you have a file with one of these extensions and when you click on this file, it does not open for you, it means that you do not have the archiver installed.
One of the most common paid archivers is WinRar, whose free period of use ends in a month (or a little more). For example, it allows you to both archive and unarchive rar or zip files.
And the most popular free archiver: 7-Zip.
7-Zip does not pack files into rar, but packs, among other things, in zip files that WinRar can also open.
7-Zip can unzip rar or zip files, including those that were packed with WinRar.
Therefore, I think that for novice PC users, and most experienced users, this 7-Zip archiver is quite suitable.
Installation and review of the free 7-Zip archiver.
The 7-Zip installation process itself is very simple. When you launch the program downloaded above, the following window will appear:
By default the folder is created 7-Zip in a shared folder Program Files(on the computer hard drive where the operating system is installed). You don't have to change anything here. Just click on the button Install and in the window that appears, click on the button Finish.
All! Ready! Let's move on to using the archiver.
Using the 7-Zip archiver
Using 7-Zip is also easy.
Unpacking compressed files in 7-Zip
Let's say you have a file that is packed with some archiver.
On your computer, this archive file will look something like this: or like this:
Since you already have 7-Zip installed, when you click on this file with the left mouse button (double click), this file will open. Everything is fine!
If you need to unpack this file, then when you right-click on it, an additional action selection menu will appear.
Find the 7-Zip line. When you hover, another submenu will open with a choice of actions. I recommend choosing: Unpack to “File Name”.
Thus, a folder is created with the name of the packed file, and all files that were packed by the archiver are unpacked into this folder.
Compressing files with 7-Zip
Let's consider the same situation, only now you need to compress the file or folder with files.
Also right-click on a folder or file. Just now choose: Add to “File name.zip”. The result is an archive (packed file or folder with files).
If desired, the resulting archive can be renamed by also right-clicking on it and selecting the function: Rename.
Please note that you also have the option to choose: Add to “File name.7z”. Extension .7z This is a type of archiving that belongs directly to the 7-Zip program and packed files with this extension are intended to be opened by the same program.
This means that if you pack files with your 7-Zip program with the extension .7z In order to give this archive to someone, then for that user to open this file, he must also have the 7-Zip archiver installed.
And since not 100% of users use this program, I recommend packaging files so that the extension is .zip(as shown in the picture earlier). This way you will be sure that the person to whom you are sending this file will open it (if he has another archiver installed).
To solve this problem, go to the menu Start-> 7-Zip-> as shown in the picture:
There in the tab Language select again Russian language(even if it is already selected), click Apply and then OK:
Reboot the computer for the settings to apply to the context menu.
Updating the 7-Zip program
The program version described in this note is 9.20. And it is sufficient for the tasks described above (and not only). But developers improve its functionality from time to time.
If you want to download the latest version, you can do this on the 7-Zip program website.
To summarize: Archivers are used to reduce file size. If any file with the extension .rar or .zip does not open, then install an archiver for yourself. 7-Zip, featured in this post, is an excellent free alternative to the paid version of WinRar.
Unpack the files into a folder as shown in the picture and, if you need to give the archive to someone, pack it with the .zip extension.
7-Zip is a world-famous free archiver with free source code. The utility is compatible with almost all known archive formats. Plus, it has a built-in manager as a convenient shell. Command line control is also provided.
The manager has a file testing function. When activated, the number of files and the total size of the archive (in original and compressed states) are displayed. The number of errors found is also shown if the file suddenly turns out to be damaged. In this case, the user will not be able to open the archive, but it can be restored using or similar programs. But some zip archives cannot be opened due to incorrect headers (incorrect file encoding). In this case, it is better to use or.
The program is very easy to use. It is not necessary to run it to unpack or pack a file - just right-click on the desired file and select the desired action.
7-Zip has already stood the test of time: developers continue to work on improving the utility for more than 15 years. During this time, the archiver gained wide popularity and became one of the most useful programs for various platforms.

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, ordinary 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 made 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.

Correlation of bit depth between OS and WinRAR
Without further delay, we recommend downloading the latest version of WinRAR for free for Windows XP SP 3, Vista, 7, 8, 8.1, 10 (32-bit and 64-bit). It is advisable to do this, since the new version of WinRAR works faster than the previous one, the compression ratio has been increased, and work with archives has been improved. If it is not clear which WinRAR to download: x64 or x32 bit version, download the program of the same bit size as the Windows OS installed on your computer. This way the program will show its maximum performance. The archiver is distributed in the form of two WinRAR files x32 and x64, for installation on a computer with 32- or 64-bit Windows. To find out the Windows bit rate, you need to go to the “Control Panel” through the “Start” button, find the “System type” line in the “System” section. Based on the information received, you should download WinRAR 64-bit or 32-bit for free, depending on the type of operating system Microsoft Windows XP SP 3, Vista, 7, 8, 8.1, 10 (64-bit or 32-bit).
During the installation process, WinRAR does not offer to install additional software, change the browser start page or other advertising offers. At the end of the installation, the installer will offer to associate supported files with VinRAR and integrate its functionality into the context menu of Windows Explorer.
In addition to archiving itself, 7Zip can encrypt compressed data. For this, a reliable 256-bit AES encryption algorithm is used. The program is free to download and is distributed as open source. Download 7Zip free for windows 7. The program has a simple Russified graphical user interface.
Creating an archive
7z archiver supports several data archiving formats, so it is possible to select the required archive format. By default, the program uses its own format – 7z. It is this that provides the best compression quality. ZIP and TAR formats can also be used.
If you need to restrict access to the archive, you can protect its contents with a password. To ensure a higher degree of data protection, the program can encrypt file names, which will not allow you to guess their contents by name.
Extracting files from an archive
To extract files from an archive, you need to select the desired archive or file in the archive in the main window of the 7Zip program and use the button Extract or the menu command file 7 –zip Unpack (if instead of the Unpack command you select Unzip here, the program will automatically unpack the archive into the current folder)
Performance test
7Zip contains a built-in test of computer performance when archiving data. To run the test, you must use the menu item Service - Performance testing. After selecting this menu item, the PC testing window will appear. By default, the program itself correctly determines the number of cores and threads in your installed processor. The developers of 7Zip for Windows 7 recommend running a performance test immediately after installing the program in order to be sure of its functionality on this computer.
