Free Ccleaner has a function for finding duplicate file, by name, size, and contents.
I have not used it yet, but there is most likely a way to search the archives of this list/forum.
look for "duplicates" "checksum" .
If the sums of the bits in all of the bytes in each file are the same, the files are identical.
That will even detect an "edited" file compared to a non-edited file, even though it may be the same shot, they are not "duplicates", they are "similar"!
