ARJ was one of many file compression utilities for MS-DOS and Microsoft Windows during the early and mid-1990s. Parts of ARJ were covered by U.S. patent 5,140,321 (expired). ARJ is well-documented and includes over 150 command line switches.

File format support in other software

ARJ archives can be unpacked with various tools other than the ARJ software. There exists a free software re-implementation of the tool. A number of software utilities, including 7-Zip, Zipeg, and WinRAR can also unpack .arj files.[2] For macOS, standalone utilities, such as DeArj and UnArjMac, are available.
