Binaries: 7z uses plugins (7z.so and Codecs/Rar29.so) to handle archives. 7za is a stand-alone executable. 7za handles less archive formats than 7z.exe. 7zr is a light stand-alone executable that supports only 7z/LZMA/BCJ/BCJ2.

Usage: 7za x [COMPRESSED FILE]
 * 1) Extract files
 * 2) 7zip x [COMPRESSED FILE]

This can also be used to extract files from an ISO.
