I have a rca lyra rd2762a and i would like to delete some music on it. I know how to delete music and i can delete most of it except for one folder containing about 30 songs in it. The songs still play but i dont want them in the lyra at all. When I go to delete it on windows media player a message will pop up after a few minutes saying: The I/O Operation has been aborted because of either a thread exit or an application request....What do I do to get these files out! HELP!
