I’m not sure if a duplicate finder is the right tool for this, but I’m looking for a way on Windows to scan the files in two directories and find out which files are in one folder but not the other, using a method like CRC or hashing instead of just filenames. I’m trying to merge some data that I know is almost identical, but there are a few random files that are present in one folder but not the other, and unfortunately, all the filenames are different.
For example, Folder 1 has “File1,” “File2,” and “File3,” while Folder 2 contains “FileA,” “FileB,” and “FileC.” Files “File1” and “FileA” have the same data, as do “File2” and “FileB,” but “FileC” doesn’t match “File3” or any other file in Folder 1.
