ntEasy Duplicate Finder is free with a restricted license (which can be upgraded). But beware: It will look to add browser toolbars when you install it.
dupeGuru Music Edition
dupeGuru Music Edition
ntDespite its name, dupeGuru Music Edition is not just for comparing music files. It adds the music functionality on top of a robust duplicate finding application. Using a smart filename comparison algorithm, dupeGuru Music Edition finds duplicates even when the files have different names.

ntdupeGuru runs on Windows, OS X, and Linux, and it follows a “fairware” pricing model.
Duplicate Images Finder
Duplicate Images Finder
ntDuplicate Images Finder is an open source tool that compares image files and detects duplicates based on image similarity. The matching can take quite some time, but the comparisons are much more difficult than those performed by the other apps on this list. This is an excellent app for someone who takes a ton of pictures and wants an easy way to zero in on specific images.
