I had windows users writing to me saying the zip file was damage. So i loaded my version of Windows Media Center into my VMware and tested it for myself. It extracts ok, but for every folder in the root directory (where extracted to), there is an identical file without an extension created. I have the option in the preferences to remove mac stuff on. How do I associate "Create Archive" to BetterZip? I like to use stuffit for extraction. The main reason I purchased BetterZip was for the windows friendly zip archiving.
