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. The file format is proprietary.
HAP 2.10 compresses a single file. HAP 3.00+ makes multi-file 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.
