    I do not think you can legally do it, since WinZIP is a propietary and commercial program.

    The source code for which version/component of WinZIP do you need? Why don't you look at open source compression projects?

    The main compression algorithm used is Deflate - information about it is public, see RFC 1951.
    The WinZIP file format also is available, searching for "appnote.txt" will lead to this.

    Newer WinZIP versions use other compression algorithms that are documented in public, like bzip2 (v9.0), PPMd (v10.0), LZMA (v12.0) and 7z (v12.0).

    Of course, other parts like the GUI or the file handling are proprietary, but there are open source compressors where you can look at these components.

    Damn kids. They're all alike.
