I've searched for a truly SMART duplicate finder for quite some time that would be able to discern from duplicate names as well as find duplicate file content with different file names. Searching the web, the Mac App Store and anywhere I could look... I found Deltopia's DeltaWalker and was totally beside myself at how AWESOME DeltaWalker works! I haven't been able to find a comparable duplicate file and folder finder, manger, merger, organizer... It's so much more than a duplicate comparison utility. The visual layout of the results are truly, very, very clear and well-defined, in a way that makes decisions to resolve the differences very easy. I love DeltaWalker. There's nothing quite like it around for the price and features. The ability to just step-up to DeltaWalker Oro is one you would not regret. 3-way comparisons allows an amazing way to resolve multiple location duplicate and/or modified files. For resolving duplicates in multiple locations, consolidating files, reorganizing my files, DeltaWalker is the most important utility I have installed on my Mac!
