Multiple copies of the same album

[Discopie]

Thanks Simon! - I think I can see what has happened. I've looked at the Melco on Windows Explorer and the same albums appear to have been saved in two different folders. I should now be able to delete the duplicate entries.
(I only recently purchased the Melco and my local Hi-Fi dealer helped transfer the contents of my old NAS across. I know he initially had problems rescuing the NAS drive and tried multiple times so I think this may have happened during the file transfer).
