I am trying to transfer multiple files at a time. So, I want to compress them to a file and then uncompress it.

I saw some post about using API provided by zlib.lib. A couple questions:

1) is zlib.lib ported on the series 60 devices?
2) what class and API is appropriate for my purpose?
3) where can I find the document about this topic? any sample code?

If you know any other library, please let me know too.
