Create archive
7z archiver supports several formats of data archiving, therefore, there is the possibility of choosing the desired archive format. By default, the program uses its own format - 7z. It provides the best compression quality. You can also use the ZIP and TAR formats.
If you want to restrict access to the archive, you can protect its contents with a password. To provide a higher degree of data protection, the program can encrypt file names, which will not allow guessing their contents by name.
Extract files from archive
To extract files from the archive, in the main window of the 7Zip program, select the desired archive or file in the archive and use the button Eject either by the menu command file 7 –zip Unzip (if instead of the Unzip command you select Unzip here, the program will automatically unzip 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, a PC testing window will appear. By default, the program itself correctly determines the number of cores and threads in your installed processor. 7Zip developers for Windows 7 recommend starting a performance test immediately after installing the program in order to be sure of its performance on this computer.

How to download 7zip and install on PC
The installation file exists in two versions: for 32-bit and 64-bit Windows. 7-Zip x64 runs faster on 64-bit systems. The bit depth of Windows is indicated in the line "System Type", which can be seen through "Start" - "Computer" - "Properties" - "System". Accordingly, according to the capacity of Windows, you should select and download the 7zip archiver for free for Windows XP SP3, Vista, 7, 8, 8 ..

7-Zip is a world famous free source code archiver. The utility is compatible with almost all known archive formats. Plus, it has a built-in manager as a convenient shell. It also provides control via the command line.
The manager has a function for testing files. When it is activated, the number of files and the total size of the archive (in the initial and compressed states) are displayed. It also shows the number of errors found if the file suddenly becomes corrupted. In this case, the user will not be able to open the archive, but you can restore it using, or similar programs. But some zip archives cannot be opened due to invalid 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 unzip or pack the file - just right-click on the file and select the desired action.
7-Zip has already passed 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.
7-Zip is a free file archiver with a high degree of data compression. It supports several compression algorithms and many data formats, including its own 7z format with a highly efficient LZMA compression algorithm.
The 7-Zip program has been developed since 1999 and is free and also has open source code, most of which is freely distributed under the terms of the GNU Lesser General Public License, with the exception of the unRAR decompressor code, which has limitations.
7-Zip uses multi-threading and allows you to use for compression, depending on the algorithm or format, a different number of threads. When creating archives in which files can be compressed independently of each other (for example, ZIP), the program can use up to 8 streams at a time. For the LZMA compression algorithm, the archiver can simultaneously use up to 2 streams. The inability to use more of them is due to the consistent nature of continuous compression. The LZMA2 compression algorithm does not have this drawback.
When compressing in 7z format, special normalizer filters are also used. So, for more optimal compression of 32-bit x86 code, normalizing converters BCJ and BCJ2 are used. The 7-Zip program also has an optimizing delta converter for some types of multimedia data, for example, uncompressed 24-bit images.
Compression results are highly dependent on the data being compressed. Usually 7-Zip compresses to 7z format 4-25% better than ZIP format.
The main platform is Microsoft Windows (including Microsoft Windows CE), where two versions of the program are available: with a graphical interface and a version for the command line. The console version was ported by the community of developers for POSIX standard systems under the general name p7zip. Ported versions for other systems, as well as the original 7-ZIP program, are available on the SourceForge system website (as of November 7, 2010 the program was downloaded from the site more than 109 million times).
The 7-Zip program is the winner of the 2007 Community Choice Awards in the categories of “Best Project” and “Best Technical Design”.
