"copied to my hard drive [not yet] to a disc"
Great News... and now if you want to investigate the many ways to compress files,
then that would be a nice topic for this board to explore.
We just need to identify file types (text, music, etc) and which compression tools work on each,
and what the trade-offs are for music files.
Most likely we could compress the 4-5 GBs on your harddrive to fit onto a single CD,
or maybe better if you can group certain albrums together and do a less-lost compression
and make 2 or 3 CDs.
