Question for Joe Kissell - Duplicate photos finding/deleting

[ace (Adam Engst)]

@joe doesn’t check in here very often, but there was just another big discussion about duplicate removers.

File deduplication - Tidy Up vs Duplicate File Finder vs Cisdem etc

Trying to clean up some old drives where I know there are a lot of redundant copies of folders and such. Anybody have a favorite go to deduplication software? Merge capabilities would be helpful I think… Looking at Tidy Up vs Duplicate File Finder, with Cisdem as a dark horse. Gemini seems slick but not powerful enough. My understanding is Kaleidoscope is really for comparing files to each other. thanks!
