Any good duplicate file /folder / picture finders apps?

[kristenanne77]

I am looking for a good app to help me get rid of many duplicate files and duplicate folders.
Also something for duplicate or similar pictures would be a plus.

Thanks
K

I really like duplicate detective - appears very accurate, but it's quite slow as a result. I recently cleaned up my photo archives on a fast TB RAID and it took 8 days to look through 7TB of data, so a secondary machine is needed if you need to take your laptop to work! Working on smaller amounts of data say a couple of GB, it is very much faster.
