*. rar - WinRAR compressed archive
rar is a common compression format, and rar is a patented file format developed by Russian Eugene Rochelle and is mainly used for data compression In terms of archiving and packaging, the full name of rar is "Roshal ARchive", which is translated into Chinese as "Roshal's archive".

* .7z - 7-Zip compressed file
7-zip compression format is a free and open source compression software format. 7-zip is based on the GNU LGPL protocol. The software released is completely open source. 7-zip uses a new algorithm to greatly improve the compression ratio. 7-zip not only has a higher compression ratio than zip, but also takes up less system resources than rar.
* .zip - Zipped file
The zip file compression format is another common data compression and document archiving storage format. The inventor of zip is an American Filipino. Phil Katz, the zip format was launched earlier than rar. Because zip appeared earlier, zip and the later compressed formats have some shortcomings that cannot be ignored. For example, the original zip file does not support unicode. , which can easily lead to difficulties in sharing some resources, and garbled characters will appear in compression and decompression, especially in the East Asian cultural circle.
