One problem that I have seen is the duplicate file that you remove may sometimes need to be in that folder for whatever program you are using to be able to access it correctly so duplicate or not it still might be better left alone where it's at.
A plus though is it can help you find extra copies of avi's, flv's and media to help you organize them better.
I may or may not try this one but if I decide to I know I'll just run it once and look at the locations of the files before deleting anything. I might just look at it once and wait a while before making any changes.
Anyway a link to the page the email accessed from is [here], their main site is "Duplicate File Checker" and the shorter version follows below.
