SQ2

SQ2 is what we're calling the compressed file format associated with a variant of the Squeeze software that calls itself "Squeeze Version 2".

Unlike the original Squeeze format, SQ2 supports a timestamp and a comment. The compressed data format is the same.

It's possible that this software is also known as ZSQ -- see the ZSQ disambiguation page.

Identification
