This archive format is used as an installation packet in the Unix operating system for updating, querying, checking, deleting and installing software products. The RPM archive is a database that is comprised of a single base of program packets and a large number of small databases. The system can store information about packet modifications, deletions and installations.
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.
