While we have a tag for duplicate-files, that's not exactly what I am looking for.
I have a 12tB drive which is almost full (don't ask), which I fear contains many duplicated, or almost duplicated directories (including sub-directories, so .directory trees).
It may be that a file or two has been added, a READ_ME.txt has been deleted, or an .INI file has been updated in a directory which I had previously accidentally copied.
While substantially identical, those directories would not be identified as duplicates by tools which I know.
I am seeking a tool which will help me identify directories which I might want to examine and consider merging them or deleting one.
So, basically, find directories which are X pre cent or more identical. May allow me to define X, maybe allow me to define file extinctions to compare or exclude (e.g exclude *.ini, but include *.xls).
I don't care too much about the features. I just want something that will flag to me that I might want to take a look.
While I would strongly prefer to find something off the shelf, I fear that this is yet another entry on my personal "code this" list . If you would like such a tool, please add feature requests in comments, in case I do actually ever get round to coding it.
