WD MyCloud showing music library twice it's size!

I started recently re-ripping my cd collection to itunes which I have moved to my NAS. iTunes shows I have 264GB of music and last time I checked MyCloud showed the size of music stored on it to pretty much match iTunes. HOwever, I’ve looked today and it says 540GB!!

I only found one album where songs were duplicated, can anyone explain how this has happened, and how I can return it to its normal size

This could happen if you use Smartware to backup your library to the NAS and store it somewhere else on the NAS, or if you have it on the NAS and you use Safepoint to back it up to a USB drive attached to the NAS. In both cases, the music files end up being duplicated somewhere.

Make sure that you don’t have backup shares with media sharing enabled.
