Due to sloppy backups and synchronization (with crashplan, dropbox, and manual copies going back some years), I have a large collection of files that has been duplicated, partially merged, and updated locally. It&#x27;s quite a mess. Do you know if there&#x27;s any tool that would help to identify subtrees of the whole set that are identical, similar-and-strictly-newer, or similar? How would you approach the task of trimming it down to one clean version?
