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.
This is a data compression format in the Unix system for saving work space, created with the help of the TAR container, combining several files into one archive that’s placed in a tar.z compressed file.
