Like Time Machine, the old WildFile "GoBack" program could go back in time to recover lost files. But it could also restore your current drive exactly to the way it used to be, including deleting newer files. This was useful in case you installed new software that turned out badly. Instead of just uninstalling it (and hoping that fully removed all the bad stuff) you could just revert to a time just before installation.

So, I see a lot about Time Machine's retrieving old stuff, but can it also delete new stuff?
