I though at it as an idea for a brand new application by Piriform, but it could also be a nice addition to CCleaner.
I'm talking about the ability to find duplicate files, using various, selectable criteria (same name, same size, same extension, same MD5 checksum, bit by bit comparison, etc.). It would be nice if you could select more than one criterion at time, such as "name + size" or "size + extension", via checkboxes. Another good feature could be the ability to search duplicates in a single folder, in two (or more?) specified folders and in one or more partitions/hard drives. That is: if I have two copies of a file named "goofy.jpg" on two different hard drives, I want CCleaner to tell me that (if I asked to search those two drives at the same time). Finally, it's important for me to be able to decide which one(s) of the copies that are found is to be deleted: say I want to remove "goofy.jpg" from drive C: and to keep it on drive D:, but I may also own "michey.jpg" on C: and D: and I want to choose to keep it on C:, regardless the decision I'm taking on "goofy.jpg".
I think the ability to work in maximized window mode is quite important for usability, too.
I'm quite sure the developers here at Piriform would be able to give to this app the clean and easy interface all their programs share.
If they choose to keep it stand-alone, I suggest to call it DFinder
