As best I can see, the scripts are quite limited in how they Handle duplicates and either you have to find two files and highlight them to run a comparison test and then delete one, or only the library file is amended, the song file not actually removed from the hard drive. I would love to see a script which does a pass over the entire library and identifies possible doubles which you can then delete from the hardrive or keep. It would ideally be automated so that you could elect to chose further matching files similarly like the import function in iPhoto. Many thanks to all for their input. Kevin
