Find and remove duplicate files in windows 10 without installing softwarehttps://www.youtube.com/watch?v=T0dK1vqcxcE
I would not trust propietary malware to collect info about my zoo and furry collections, try github projects or better to make your own, its not hard, chatgpt if you are struggling.
I'm not the OP but, it's simple to find files that have identical checksums, MD5 or SHA hashes, however, what good software can find identical images if one is compressed or resized?
My favorite has always been the awesome duplicate photo finder. Its free and really lightweight.
