Search and destroy duplicate files


I am wondering if there is a way to find and view duplicates, then delete all or most of them!


You did not search the forum, right?
Have alook at these threads that answer directly to the keyword "dupliate".
Display all duplicate songs

First make sure for yourself, what you define as "duplicate".
This first step can lead you to make a plan how it can be solved using Mp3tag or not.
Here is a link to a german thread ...
Verschiedene Dateien löschen
... which includes further more links to other threads regarding the handling of "duplicates".
