This is the standard format for data compression in a Unix environment. It’s used to store several files in one archive and for creating a file system archive and for software distribution. In a TAR archive, information is logged about the owner, file groups, catalog structures and file timestamps. Different bzip2 and gzip tools are used to create an archive.
This format works based on the main compression algorithm LZMA. It was originally used in 7-Zip archives. Other compression algorithms can be used in 7z since this format has open architecture for developers. It has a high compression coefficient. The encryption algorithm is AES-256.
