Duplicate File Finder
Full user review
""Duplicates" are not duplicates!"
Thorough, but only if you purchase the Pro Edition.
Some of the dupes were not dupes at all. Sometimes bytes and/or dates did not match.
A duplicate in my mind is not the same as 'something close". This free edition does not allow you to compare multiple attributes in the same search. After searching C:, I studied the results before deleting any files and found this software had included versions (minor differences) as duplicates! There are simpler, faster, AND MORE ACCURATE duplicate file finders available. I immediately deleted Duplicate File Finder 4.2.1.
