Thanks for the clarifications. I re-edited the 87 minute music instruction. I delete some minutes and broke what was left into 10 tracks. It seems that I still had only one clip, broken into 10 tracks. The only way I could save the track structure was to save each track as a separate file. I then had a total of 46 minutes of audio, totaling about 42 MB. I had initially misread the message in the Export Tracks/Clips. I have tons of GB, not KB as I said in my original question. My remaining question is, when I am in the Sound Editor screen, why, under the Export heading, won't my track structure save when I click Export Tracks/Clips? I finally saved each track as a file, track by track, and burned a CD containing all ten of the edited tracks. I did what I wanted to, but it seems that the Roxio Creator 12 application can do loads of things, but instruction is minimal.
