What is ARJ file?

An ARJ file is an archive file in which one or more files can be archived and compressed. The ARJ format was especially popular at the time of MS-DOS, but has since been completely replaced by rar and zip. Arj supports long filenames, file versioning, data integrity protection, and distributing an archive across multiple files. (these then have the ending a00, a01, a02, etc.)

However, there are a number of free and commercial pack programs that can handle ARJ archives. These usually have a graphical user interface, but can only unpack ARJ archives.
