When you add songs to your iTunes Library, those songs are added to the Music folder in the iTunes section of the computer. Sometimes, however, you may get an "iTunes Access Privileges" error that prevents you from adding songs to your library. This error is associated with the permissions you have set on the computer, and can be remedied by changing the computer's permissions.
What are Access Privileges?
Like any computer program, iTunes cannot modify a file or folder that it does not have permission to modify. ITunes' access privileges are determined by whether iTunes has permission to access a file or folder. If it attempts to access a file or folder that it cannot modify, the user is prompted with an "access privilege" warning.
Access Privilege Warnings
If you attempt to add music to iTunes via drag and drop, CD importing or making a purchase from the iTunes Store, you will get one of three access privilege warnings. If you attempt to drag and drop music, you will get the following error: "Attempting to copy to the disk 'your hard drive name' failed. You do not have enough access privileges for this operation." If you attempt to import a CD, you will get the following error: "Error occurred while converting the file 'song name'. You do not have enough access privileges for this operation." Finally, if you attempt to purchase music from the iTunes Store, you will get the following error: "There was an error downloading your purchased music. iTunes could not save to your Music Folder because you do not have write access. Check the permissions on your Music Folder, then use the Check for Purchased Music command in the Advanced menu to try again."
Changing Windows Permissions
To give iTunes access privileges, you must change the permissions for the folder it is trying to modify. Since iTunes is a music application, the folder it is attempting to modify is the computer's Music folder. Click the "Start" button, and select the "Computer" option. Locate the computer's Music folder, right-click on it, and select the "Properties" option. Click the "Security" tab, followed by the "Advanced" option. Click the "Owner" tab, followed by the "Edit" button. Click on your username in the "Change owner to" box, and click the "OK" button to save the changes. ITunes will be able to access the folder.
Changing Mac Permissions
If your computer is a Mac, click the "Finder" icon in the computer's dock and locate the computer's Music folder. Right-click on the folder and select the "Get Info" option. Click the lock icon and enter your administrator password when prompted. Click the arrow to the left of the "Sharing & Permissions" heading, and click the option listed to the right of your username. Select the "Read & Write" option from the drop-down menu that appears to change the permissions. ITunes will be able to access the folder.
