This article mainly introduces what file.7z refers to in the computer, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

".7z" is a compressed file that can be opened using 7-zip, WinZip, good compression, fast compression and other decompression software, where 7-zip is the official tool for 7z files. 7z is a compressed file format, which is a compression format for 7-zip compressed files. It uses LZMA compression algorithm, and the compression ratio is very high.

".7z" is a compressed file, and 7z is a mainstream efficient compression format with an extremely high compression ratio.

In computer science, 7z is a file format that allows data compression using a variety of compression algorithms. This format was originally implemented and adopted by 7-Zip, but this file format is public, and the 7-Zip software itself is open source under the GNU Lesser General Public License (GNU LGPL). The latest version of the LZMA Software Development Kit is V9.34. The MIME type for 7z format is application/x-7z-compressed.

Usually 7z files using 7-Zip can be 30-70% smaller than zip files.

And the zip format created with 7-Zip is 2-10% smaller than most other compression software.

Files with the extension ".7z" can be decompressed by winrar, 360 compression, fast compression, good compression, winmount, winzip and other software under windows.

7z is similar to rar we see on Windows platform;7z has a high compression ratio, at first it is the compression format supported by 7-zip, but officially because 7-zip is an open source original, 7z is also supported by most compression software;

7z format characteristics

Open source and modular component architecture (allowing any compression, transformation or encryption algorithm)

2, the highest compression ratio

Strong AES-256 encryption

4, can change and configure the compression algorithm

5, support large files (maximum support up to 16EB)

Unicode file name support

7. Solid compression is supported, allowing files within a class to be compressed in a stream, so that similar content is effectively compressed.

Supports file header compression for files

Support multithreaded compression

The 7z format supports 256-bit key-key AES encryption. The key is derived from the SHA-256hash algorithm on the user-supplied secret code (using a large number of iterations to make brute force decoding of the secret code more difficult)

Thank you for reading this article carefully. I hope that Xiaobian's article "What file does.7z refer to in the computer" will be helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
