Being that I don’t have negative hard disk space, I needed to find a way to install the Jam Packs and other audio content to an external drive. I figured that maybe all I would need to do is just put in the Jam pack discs and it would let me install. Wrong, all I got was a file that said use the Logic installer. Apparently the files on the disk are hidden. But doing a little search in google I found a help article on the apple site that explains everything I wanted to know.
Apples help article on how to install Logic content to a different location
Update: It took a little over 2 hours to install the extra content. However I was disappointed to find that there was no option to install the Jam Pack Instruments to a different location. So in the end I just ended up installing the Apple loops and the SoundTrack content.
