I needed to free up some disk space for iMovie so I backed up and deleted 20 GB of MP3 files which were used by iTunes 2.
Now, I have just installed a big disk drive which provides ample room for my MP3 files.
However, in the mean time, I had installed iTunes 3 -- and it still shows all the files that are no longer on my computer.
I would like to:
1) clear out the iTunes file list,
2) restore the 20 GB of MP3 files,
3) have iTunes generate a new file list from the installed MP3 files.
How do I do this?
