File format support in other softwareEdit

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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> For macOS, standalone utilities, such as DeArj and UnArjMac, are available.
