What is the best duplicate file finder, that preserves my source of truth? (alien.top)

Having been so meticulous about taking back ups, I’ve perhaps not as been as careful about where I stored them, so I now have a loads of duplicate files in various places. I;ve tried various tools fdupes, czawka etc. , but none seems to do what I want.. I need a tool that I can tell which folder (and subfolders) is the source of truth, and to look for anything else, anywhere else that’s a duplicate, and give me an option to move or delete. Seems simple enough, but I have found nothing that allows me to do that.. Does anyone know of anything ?

If you're 100% sure that the dupes are only between your source of truth and "everything else", you can run fdupes then grep -v /path/to/source/of/truth/root the output - all the file paths that remain are duplicate files outside your source of truth, which can be deleted.
