Duplicate file finder
Is there a tool that can identify/manage duplicates at the directory level? I've tried using duplicate file removal software to weed out duplicates, but these applications are too granular. I am looking to manage my duplicates at the folder level. Most of my duplicate files are also in (nearly) duplicate folder structures, so I want to to be able to identify the root (nearly) duplicate folder and delete/merge/update the root folder, instead of managing duplicates on a file-by-file basis.
One of the ways these duplicate folders was created was because whenever I upgraded to a larger harddrive, I backed up the old harddrive contents to a folder on the new harddrive. I have several directories filled with duplicate files and directories. Some directories are super-sets of other directories (contain the same files/directories plus additional files) Others contain a common subset of files/directories, but each contain additional files.
