I have burned an audio books on a CD-R for my mom. This disc I burned from didn't need the whole disc but, somehow I burned the first part again on the CD-R remaining room. I want to erase just the last few recordings and not the whole disc. How can I do that?
 
Sure, it is a quote by a former NYC mayor -- Ed Koch. It just fits many threads. :lol:
