My stuff is mostly video if it makes a difference. 2 X 24tb raids and plenty of 1tb SSDs. Plus local space on about 4 machines I guess totalling another 8tb. Probably closer to 75TB total thinking about it.
Was hoping Hedge or somewhere would have a solution.
CCleaner has a built-in duplicate file finder. There are other specialised programs too which may be more suitable for 60Tb
