ZPack File Format, spec and tools
Posted by Sachin Garg on 10th May 2006 | Permanent Link
Today at comp.compression, Brendan G Bohannon announced a vaguely PAQ like file format supporting compression and read/write operation (as zipfiles are not that well suited to read/write). The format will assume no fragmentation of smaller files, rather a file is to be moved if it expands beyond the space available to it.
Current default file extension will be “zpk” and will use deflate with a 64kB window. The CRC algo will be the same algo used in ZIP and PNG for example.
You can checkout the code and format specs.

Where did ou get this file from? How did you create it?
Can you tell what are the first few bytes of the file? it might or might not be a zpack file.
