Dumb question - is Winzip supposed to be able to read the zlib format? I usually use it to decompress .zip or tar.gz archives.
Well I made that assumption because Winzip and XP both maintain associations for the .z extension. This is from the Winzip help file: <snip>
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.

Thanks. I guess my use of the .z extension in the zlib example is misleading. Maybe I'll leave off the extension altogether. Jonathan
