--- Comment #21 from Vincent Povirk madewokherd@gmail.com 2009-11-23 22:22:52 --- This isn't the place, but Wine cannot provide any real security. It has no ability to prevent a Windows program from making native system calls and accessing the native filesystem. Removing z: at best provides security by obscurity, and it's confusing, so it's not recommended.
