Use the 7z compression and decompression tool-command line

Compression: "A" belongs to the 7z compression command; "-R" belongs to the 7z parameter, indicating Recursion

7z A compressfilename Source
7z A compressfilename source-R

Extract: "X" is a 7z decompression command; "-o" (letter O) is a 7z parameter, indicating that the output directory is followed by the directory path, absolute or relative path (starting from the current directory)
7z x compressfilename
7z x compressfilename-o
Note: Although "e" is also a 7z decompression command, unlike "X", it seems that all files are decompressed to the current directory or specified directory, the specific rules are unclear, and the extracted files are messy.We strongly recommend that you use the X command.

Volume compression:It is basically the same as the command or parameter used for compression, except that there is an extra "-V" parameter, followed by the size of each volume. The unit can be B, K, M, G

For other help information, see the following 7z:
