Possible to configure 7 to auto-wipe files?
I'm in the process of transitioning to Windows 7 and exploring the new capabilities that come with it. One feature I've long wondered about and considered potentially useful (but never actually ran into in the real world) is a OS/filesystem option which if enabled would cause the OS/filesystem to automatically perform appropriate wiping in response to events such as file deletion, the shrinking of files, shortening the name of files, completion of journaling steps, perhaps some other cases. Is it possible to configure Windows 7 to do that, be it via built-in existing capability or addon?
Note: I'm aware that there are various programs that can be user-invoked or scheduled to wipe specific files, wipe slack/freespace, that sort of thing. The feature I'm attempting to describe is one where wiping is more automated and integrated.
