That is because you are expanding the .zip in Windows, the __MACOSX  
directory is an invisible directory created by the Mac OS for extra  
files used by the Finder.

The other directory is an .app, that is the VM is a "bundle", the  
trick is in the mac the finder shows the bundle as one file not as a  
directory.

So expand the .zip in a mac, don't bother with windows.
