I am new at downloading music, but not sure how to save my files (currently 4,500KB)to a smaller size to store as data on a CD. A friend once gave me a CD with over a 100 songs. I use a TDK 40/12/48x CDR. My computer is a Compaq 5000, Windows (Mel). The software I use for burning is TDK Digital Mixmaster (also has Nero). One note (which will probably help you answer): when I go to burn a CD, the drop-down box will show "would you like to"; - Record an audio CD - Record a CD ROM - Copy a CD - Create 'Aiff audio' file - Create Twin VQ Version 2.0++ format audio file -Create PCM wavefile audio file (I really do not understand what the final 3 selections actually do)Normally, I select one of the top 3, BUT I noticed that in the next dialog box, a selection "Create a new data compilation" is available to check. (I'm not sure what this is either. Sorry! I really am a newbie and really appreciate your help!!
