There is a piece of software called CloneSpy that is a utility for finding duplicate files. I like the user interface. https://clonespy.com/features/ https://clonespy.com/features/ I find it useful for finding that I have four copies of a 50MB pdf in different folders, that kind of thing. If I want to free a few gigabytes of diskspace without too much mental effort then a scan to see what the biggest files that I have more than one copy of can work for me. It is Windows only and closed source. I presume it calculates a hash for every file then compares the hashes. I would like a version that I can run on Linux and that nicely handles things like filenames with unusual characters.
