[G4] iTunes library on another disk

[Ernest Vincent Pons-Worley]

You can easily put your iTunes music on another hard drive to save  
space on your boot drive.  I recommend that you make sure your iTunes  
music is backed up before you do this in case you erase the wrong  
file by mistake.

First, exit iTunes (the application shouldn't be running when you do  
this procedure).  Open two finder windows and select the boot drive  
in which you have your current music folder in one window and the  
drive where you want to store your music on the other.  Drag your  
music folder from the window of the boot drive to the window of the  
new drive.  All the music will copy over.  This may take a while if  
you have a lot of music.  Once it's copied, open the music folder and  
open the iTunes folder on the window of the boot drive.  Delete the  
iTunes Music folder.  (It's backed up, right?)  Empty the trash.  Go  
to the window of the new drive, open the music folder and open the  
iTunes folder then make an alias of the iTunes Music folder.  Drag  
the alias to where the iTunes Music folder was that you deleted on  
the other window.  Rename the alias iTunes Music (just get rid of the  
word "alias" in the file name).  When you launch iTunes again it'll  
see the music in the library just like before but it's actually  
getting the music off the new drive.  Of course, if you're using an  
external drive, it has to be mounted before you launch iTunes or it  
won't find the music.
