Quantum is a compressed archive utility, and associated file format, developed by Cinematronics corporation. It runs on a normal computer, not a quantum computer.
Contents[hide] |
[edit] Discussion
As of v0.97, the distribution includes:
- PAQ.EXE - Compressor for DOS
- UNPAQ.EXE - Decompressor for DOS
- QWIN.EXE - Decompressor for Windows 3.x
The software (at least for v0.96-0.97) is consistently named "Quantum", despite filenames that may suggest other names.
[edit] Identification
Files begin with bytes 'D' 'S'. The next byte (the major version number) is probably always 0x00.
[edit] Specifications
- quant097.zip → QUANTUM.DOC → "Archive file format" section
- Quantum compression format
[edit] Software
[edit] Sample files
[edit] Related formats
- Some Microsoft CAB files use the same "Quantum" compression scheme as this format.
