I am actually dealing with this on 2 different PCs. One old and one new where I am putting the library on a larger secondary drive. The new computer is the only reason I found out there was a problem, by the way. Anyway, the solutions in this thread have totally failed to work.
I had copied the old files from an second drive to the main drive on the old computer. But, nothing would allow me to permanently change the iTunes media folder. In desperation, I spent last night using the "Create New Library" option after doing the Shift+Click, and then downloaded just the movies to the new drive. That took all night, but it worked--mostly. Movies I obtained on iTunes via promotions are not recognized as being purchased. So, I no longer have them on that computer. I then deleted the old files.
HOWEVER! After hours Google searching last night and today, I pieced together a solution that worked on my new computer.
I had taken the hard drive with the iTunes Media files from the old computer and installed it on the new computer. However, iTunes would not let me change the default download location, or recognize the files were in the new location. So, here is what I did:
- Launch iTunes by holding down the Shift button and double clicking on the icon.
- Choose the option "Create New Library". This will create a new Library on whatever drive you choose. AND i Tunes will remember that as your default location.
- In iTunes, go to File--> Add FOLDER to Library. Choose the pre-existing Library folder.
- iTunes will link all the old files from whatever folder you have them in to the new iTunes Media location.
IMPORTANT: ITUNES DOES NOT MOVE THE FILES. It simply creates/remembers the pathway to the files. So, if you get rid of that drive, be sure to back up your files and tell iTunes to link the new folders.
IMPORTANT: I am working on PCs, not Macs. I have no idea if this will works for Mac systems, though I suspect it will.
I hope this works for y'all. And, I hope Apple gets off their lazy butts and fixes this bug.
