The ".Z" extension is conventionally used for files compressed with
the Unix "compress" program, which uses LZW.  zlib and gzip were
created to provide a patent-free alternative to it.  They use the
same compression algorithm as PKZip and WinZip but do not use the
PKZip file format.  I doubt that WinZip has any support for raw
compressed files.
