Locate and delete duplicate files on PC - Windows OS?

Question

I have recently discovered that there are a lot of duplicate files on my parents computer. - Identical images, identical file names, stored in different folders.
Is there a simple way to search for any duplicate files so that any duplicates can be deleted?
I don't mind purchasing some software, but don't want to spend a lot as I hope it will be a once off clean up!

Thanks!

I think clone Remover is a good program for this problem:

and this version is portable and don't need to install:

I haven't used this but it looks like it might do the trick.

EDIT: Here's the Google results for the search I ran.

http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-GB%3Aofficial&hs=1N1&q=duplicate+file+finder&btnG=Search



And here's the same result with freeware added.
