JRchive is a compression/archiving utility, and its associated file format. It was developed by John Ross and JAYAR Systems. There were versions for DOS and Unix. The DOS version was distributed as shareware.

[edit] Self-extracting archives
Self-extracting archives are supported, though creating them is a manual process. They use EXE format.
[edit] Identification
Files start with the ASCII signature "JRchive". In all known versions, this is followed by "10".
Self-extracting archives start with the bytes in the included "SELFEX" file, which is different in each version. They have an embedded archive in the overlay segment (refer to MS-DOS EXE#Special file positions).
[edit] Software
- JRchive - DOS shareware
- v1.01 (1992-05)
- v1.02 [release 1] (1993-11)
- v1.02 [release 2]
- v1.10 (1995-05)
The two v1.02 releases are the same, except for the documentation.
