ARJ is an archiving program created by Robert Jung for IBM-compatible computers. The letters stand for "Archive Robert Jung."
ARJ compresses files to save storage space and speed transmission when moved from one computer to another. The program has long filename support, file version management, archive merging, password protection, data damage protection, a digital signature option, recurse directory support, ANSI escape sequence display handler, configurable command options, handling of up to 99 volumes, ability to store up to 250 backup s per archive, ability to work with duplicate filenames within archives, and archives that span diskettes.
There are two versions of ARJ currently available, called ARJ and ARJ32. ARJ runs in DOS (Disk Operating System) 2.11 and above, and requires only 512K of random-access memory ( RAM ). ARJ32 runs in 32-bit Windows 95 and later systems. Either version can work with files of up to 1 gigabyte , and can process a drive larger than 2 gigabytes with its multiple volume feature as long as any individual file is not larger than 1 GB. Both ARJ and ARJ32 are available in English, Portuguese, German, Polish, French, and Czech.
