ZSoft ZPK2

ZPK2 is what we're calling a certain compressed installer-archive format used with, at least, early versions of PhotoFinish by ZSoft.

Filenames have an extension ending in "$". This is a little misleading, as ZPK2 is definitely a multi-file format.

ZPK2 appears to be a relatively simple format, similar to CP Shrink. It uses PKWARE DCL Implode compression.
