ZPAQ (or zpaq) is a compressed archive format, and associated software. It is a member of the PAQ family of formats.
Apparently, a capitalized ZPAQ usually refers to the format, while zpaq refers to the software.

[edit] ZPAQL
To the best of our understanding, ZPAQ decompression algorithms are written in a special programming language called ZPAQL (which apparently uses the .cfg file extension), compiled to bytecode, and stored in each ZPAQ archive. This allows ZPAQ to use practically any compression algorithm.
[edit] Identification
Most or all ZPAQ archives begin with ASCII "zPQ", or "7kSt".
