From Just Solve the File Format Problem
- Not related to QuarkXPress.
QuARK (also written QuArk, Quark) is a compressed archive utility for DOS, and associated .ARK file format, developed by Robert Kunz.
(Based on educated guesswork.)
Files start with bytes
0x37 0x04, and have
0x37 0x03 (a marker for the first member file) at offset 8.
The byte at offset 2 is a version number. Known values are
0x10 for v1.00beta,
0x16 for v1.06.
- QuArk v1.00 beta - Russian and English software, Russian documentation
- old-dos.ru: QuARK → v1.06 - Russian software, no documentation
