CAR (MylesHi!)

CAR is a compressed archive utility, and associated file format, developed by ''MylesHi! Software'' / Chris Campbell.

Identification
This applies to the CAR files produced by version 1.50, which was the first release, and the only one we know of.

CAR format is very similar to LHA format, but it has the header fields in a different order, making it completely incompatible. Unfortunately, it is difficult to reliably distinguish the formats, and maybe impossible to do with perfect accuracy.

A CAR file has the following properties (but so do some valid LHA files):
 * ASCII "" or "" appears at offset 2
 * {the byte value at offset 0} = {the byte value at offset 15} + 25
 * bytes appear at offset {{the byte value at offset 15} + 24}

Specifications

 * car150.zip → CAR.DOC → Appendix G -- CAR technical information

Software

 * CAR v1.50 (DOS software)
 * - Can convert CAR to LHA
