It turns out that my son loaded all of his music on my SSD instead of the data drive, meaning that there is very little space on the SSD. I would like to move the iTunes library to the data drive. I found this article: http://support.apple.com/kb/ht1449 and I started following the steps. In step 11, it says to go to File > Library > Organize Library, then Consolidate files to move the files to the new location. I tried that in his account and it says "Copying files failed, because you don't have permission to change your iTunes Media folder or a folder within in it." I immediately figured that was because his User Account is not an Administrator account. So I made him an Administrator and tried the same thing. Same result. What is the problem?
