From Just Solve the File Format Problem
Hyper archive (HYP) is a compressed archive format associated with an MS-DOS utility named Hyper. The utility was developed by K. P. Nischke and P. Sawatzki, and distributed as shareware.
A HYP file begins with bytes
1a 48 50 (if the first member file was compressible), or
1a 53 54 (if not).
Self-extracting HYP archives in EXE format are supported. They are constructed manually, by appending a .HYP file to a copy of the main HYPER.EXE file. In such a file, the archive data is embedded in the overlay segment (refer to MS-DOS EXE#Special file positions).
- Format info from Corion.net and FileFormats.Info
- There is some format information in the HYPER.REF/HYPER.DOC file included in the distribution.
- Hyper v2.5 (English)
- Hyper v2.6 (German)
- Hyper v2.7 (German): CD Direkt 1995 03 → CDD/DIREKT/WIN/SF_PRG_2/INSTALL/HYPER.EXE
Hyper v2.7 (assuming it's legitimate) has only been found as a bare executable file, possibly only as a component of something called SF Install.
