What is the crowd's opinion of Duplicate File Detective?

From 3.5 billion comments

It exactly what you are after. For Windows the best dupe tool I have found is https://www.duplicatedetective.com/.

I like that I can scan multiple folders then select and delete the dupes that are in one of those folders.

    Depends, when you say "duplicates," do you mean "I used burst mode and ended up with 20 photos of the same thing every time I took a picture of something" or do you mean "the same file was duplicated repeatedly?" Sounds like the latter.

    In that case, I recommend Duplicate Detective. I use it myself to de-dupe. It does a fantastic job. Very robust in its configuration options for determining duplicates. You can set a confidence threshhold, you can tell it if it should consider files as the same based on: filename, hash, meta data (for certain file typets) etc. It'll search your drives and give a report of all the duplicates it found. You can sort the report, chose which copy to to keep, or tell it "just keep one copy of everything." It's flexible, it's trustworthy, it's thorough. Give it a try.
