Duplicate file finder?

[Ghostwheel]

Anyone know of an app that will search for and list duplicate files? For use in large music/photo/media collections, etc...

 

[Ghostwheel]

...Nothing? Not a single file manager or other app that can do this yet?

Guess I know what my first attempt at writing my own app will be.
