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 is an archive with files compressed with the help of the ARJ algorithm. It supports long file names; file management splits data into several files by size to protect data integrity. It was originally developed for earlier versions of Windows and DOS. Currently a version with open source code works with almost 10 different operating systems.
