I know it seems like an arduous task, but I need to generate a list of duplicate files on a server (name, date).. not so much so isolate the files.. more the home drives of people who are making the same copies of folders as a bastardised way of archiving.

So far I have found 2 people who managed to waste 30gb space by this ridiculous way of archiving. Unufortunatly I dont want to manually scan 1500 users

Any cool cool considered, thanks in advance
