Compressia

Compressia is a compressed archive utility for Windows (32-bit GUI), and its associated file format. It was developed by Yaakov Gringeler. It was noted for having a good compression ratio.

It's not clear when it was first released, except that it was sometime between 1998 and 2002.

The formats used by different beta versions are not necessarily compatible with each other.
