Is it possible to be implemented a tool for searching  double (by size, name, tag???)?

Thanks, I will try dupeGuru almost it could be pretty have tool in gmb.

you could try to write a plugin that does that  ;)

FSlint seems to be a pretty tool to : http://www.pixelbeat.org/fslint/

I get rid of duplicates by sorting to Song Title, duplicates are bunched together. You can find them by traversing the playlist and then get rid of the duplicate ones.
