提供了zip压缩解压缩的源代码 对于需要这方面的朋友希望有用

================================
For Wiz 5.0/6.0:
================================

   o add multi-part zipfile handling

     top of the list!

   o add new low-level, binary API

     very soon (maybe 6.1)

   o add option to search zipfile contents for a string and print the
     results? ("zipgrep" option).

     way, way later, if ever...
