I had all my music on a hard drive connected to my desktop. That drive was
name J:

I moved all my music to my laptop's hard drive, C:, to take to work and
reorganize and get all the file names the way I wanted them. I want to make
some playlists on my laptop, and then transfer them over to my desktop. All
my music will be going back to the J: drive on my desktop.

My question is this: If I make the playlists on my laptop, they will read
the location of the music as being on the C: drive. Is there anyway to make
a change to get the playlists to read from the J: drive when I copy them over
without having to completely remake them from scratch?
