This article describes what the ARJ compressed file format is. It also explains how to open an ARJ file and how to convert an ARJ file to another archive format.

What is an ARJ file and how do I open it?

A file with the ARJ file extension is an ARJ compressed file. Like most archive file types, they are used to store and compress multiple files and folders into one easily manageable file.

ARJ files can be opened with any popular compression/decompression program. We recommend 7-Zip or PeaZip, but there are several free zip/unzip tools to choose from, including the official ARJ32 program.

If you're on a Mac, try The Unarchiver or Incredible Bee's Archiver.
