Install Linux 7zip: sudo apt-get install p7zip p7zip-full uninstall rar-related packages that may have been installed (default is not installed ): sudo apt-get remove rar unrar after this operation, when extracting rar and zip files, file-Roeller (archive manager) will automatically call 7z to decompress the files, while 7z can recognize Chinese encoding, there will be no garbled characters. decompression and compression are all performed through the file-Roeller operation of the graphics program, and no command line is involved. If you do not unmount rar from www.2cto.com, file-roller uses rar to decompress it by default. rar cannot recognize Chinese encoding, so garbled characters may occur. Of course, you cannot create rarfile on Linux, but is it necessary to package it into rar format? Although unrar can recognize Chinese encoding, it is not a free software like rar. they are all commercial software of WinRAR. since 7z can extract rarfiles, why should I use it? In short, file-Roeller uses 7z to decompress 7z/rar/zip by default, and 7z is used to create a 7z/zip package. Therefore, the 7z format ensures that your compressed package is not garbled. When creating a 7z package in Linux, you can also encrypt the compressed package directory as in Windows.
