This info-zip code will not create a zip file structure.
There was a Milan Kosina sample in May 1998 FPA about using this in VFP.

There are a lot of free dlls and ocxes which use this code,
for example www.foxbrasil.com.br/downloadut.html contains some list of them for foxpro.

However, no one of them will produce a zip file structure.
Also I need a multi-disk zip structure.

I'm thinking about using zlib for compression and creating zip file
structure using foxpor file i/o operatsons.
