JAR is a PC file archiver that compresses files into a disk-space-saving archive using state of the art archiver technology. It is fast, powerful, reliable, and has a rich set of features (see below).

JAR has a similar command and option feature set to the PC archiver ARJ, but it is not archive compatible with ARJ. JAR comes in a 16 bit DOS version and a 32 bit Windows version.

JAR is not related to the special ZIP archive scheme (Java ARchive) developed by Sun Microsystems.
