I have been hunting for an app or set of scripts that will perform cruft cleanup (remove junk files; clean temp folders; browser caches; etc.) on drives that are not in an active system. So far all that I've evaluated only work on an active system. Does such a utility exist or do I have to write my own set of scripts?
Although I am hesitant to actually recommend it (CCleaner is dangerous and 99% useless)
CCleaner does have an Enterprise Edition which allows you to work with machines across your network.
Another app that seems to do this fairly well that I've been playing with is CleanUp! I'm not yet sure how effective it is on newer Windows OS releases, but it seems to have some real potential as it offers a preview run as well.
