What is Info-ZIP?

From windows Commande Help

Info-ZIP is a group of C programmers, with the goal of offering a free ZIP packer and unpacker on as many platforms as possible. With their permission, we translated parts of their code to Turbo Pascal and integrated it into Windows Commander. The condition was that we did not charge additional fees for their code and that the source code is free (see below).

The Chief contributor to the unzipping code was Mark Adler. Special thanks go to him for making it available for free!

or on some simtel.net mirrors. Our code will be available in the future on some Internet hosts (look for info-unz.dll).

The ZIP packer uses the ZLIB library by Jean-loup Gailly of info-zip. I didn't convert it to pascal, but put it in the DLL wcmzip16.dll. ZLIB is available at the same site on the Internet.
