Placement of library.

Hi Guys,

Been trying to find the answer to this one, but no luck so far. iTunes has put it's library (of mp3s) under users on my c: drive, which is now rapidly getting filled up. I have used the advanced options to redirect it to a folder on my d: drive but it still seems to want to leave the data on the c: drive. Am I just misssing something here ? Have stopped adding anything to the ipod to avoid overload on c:

Many thanx,

Colin.
