Just Brilliant!

It’s got a feature that creates an alias shortcut that you can use in place of the duplicate file which will direct you to the remamining copy! Not super intuitive but well worth it after you you do a little digging around. Although this thing can really fill your trash bin, mine appeared empty despite have loads of files in it. The key is emptying your trash bin out after you use this app.
