HAP (or Hap, or Hap and Pah) is compression software for DOS, developed by Harald Feldmann and Hamarsoft.
There are probably just two publicly-distributable versions of HAP: v2.10 and v3.00. There are other versions that are commercial software.
HAP 2.10 compresses a single file. HAP 3.00+ makes compressed archives.
The HAP software consists of a "HAP" program for compression, and a "PAH" program for decompression.
Identification
V3.00 files start with the byte 0x91, followed by ASCII "3HF".
V2.10 files seem to start with bytes 91 4a 2e.
Software
Note that the 3.x releases below all contain the same software. Only the documentation is updated.
