Quantum is a compressed archive utility, and associated file format, developed by Cinematronics corporation. It runs on a normal computer, not a quantum computer.

[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.
