Import playlists in a NAS drive

[carocci]

I bought a NAS drive where I put all my music. Now, without using any PC, I can listen whatever I want with my Sonos. To do so, I just have made a sync between my music folder on the PC and a new folder on the NAS drive. All works perfectly except all my playlists (and with 7.000 mp3 they are really useful!) because obviously they remain with the old path of my PC and not linked to the new folder. Even if I try to change them manually, after a new sync (with new MP3) I will have the same problem. Any idea to solve this issue?
Thanks,
Simone

Hi Simone - I just saw that you hadn't had an answer...

Could you provide more info please. What are the playlists that you're trying to import? Are they in iTunes or another program?
