TPK is a compressed archive format that was used by some software installers. It was apparently used mainly in Germany.
Its origin is uncertain, but it might have been developed by Thomas Haukap, author of software named VoiceConnect.
Format details
TPK is clearly a derivative of LHarc/LHA, though it has significant differences.
The main "TK1" compressed data format is identical, or at least very similar, to LZHUF file format. That is, it's the same as LHarc's "lh1" scheme, except that it starts with four bytes containing (an extra copy of) the uncompressed file size.
Identification
At offset 2 is a compression identifier: either ASCII "-TK1-" (if the first member file is compressed), or "-TK0-" (if not).
Sample files
- Pegasus Vol.3 → (CD1) → PEGASUS/WIN31/DFUE/VOICEC30.ZIP → most *.TPK files
- [1] → { NRGXTME*.ZIP → XTMENG.A* (multi-part ARJ archive) } → *.TPK
