Please use the search to find discussions and feature requests on the topic of duplicates, e.g. dating back to 2007:  
[/t/5934/1](https://community.mp3tag.de/t/5934/1)

The basic question is still unanswered: what defines a duplicate?  
The filename? Rename it, easily.  
The title? Is it really a duplicate or just badly tagged and you see the radio edit instead of the video version?

In any case: you actually have to listen to the files and see what you have. Any kind of automatism only fogs your view on the quality of your collection as it irons out the rough spots instead of pointing to them.
