This format works based on the LZMA principle compression algorithm. It was originally used in 7-Zip archives. tar.7z archives were created for storing info about file owners and for ease of use in Unix systems, based on a TAR archiving tool.

This is one of the most common file compression formats. It was created by Russian programmer Evgeny Roshal. The format allows one to break up an archived file into several parts, to block an archive to prevent accidental modification, and to enhance data recovery (helps to renew a damaged archive). It has a 128-bit AES algorithm.
