I am under the assumption that you are trying to delete the music from you
harddrive, you did not state, for you cannot delete them from a CD-R
You can go to: Start/Search/type *.MP3 (if they are in that format
highlight them and rightclick Delete. That will delete all MP3s foun
on your harddrive. If they are in an other format use the same procedur
but type the proper extension format, i.e. *.cda or *.wma or *.wav etc.
