Good finding - no help with selecing instances to remove
The tool looks solid when searching and finding duplicates in one or more locations!
Unfortunately it then offers no help to select the files to remove.
This could be done by describing who preferred paths look like and/or where never to delete. Ideally a list of path-REGEXs sorted in the priority for keep/delete.
Unfortunately I cant find the option to replace file by a link instead of deleting it completely.
Workaround: "Export results" (to csv with "Group-ID;selected;path" fields) - a little scripting with grep & awk & xargs should help around both weaknesses (at least the "delete only in preferred places" should be easy - yet not as easy as some GUI update)
