Hello! I have recorded some lectures with my sansa clip+ 4gb. It’s pretty good for that but I have annoying problem. If I record longer voice clips. It doesn’t remove the clips. It says it deletes files but they stay there. If I delete in windows it doesn’t show them in windows but when I open clip they’re still there. If I record smaller clips it works but If I record over an hour they stay there. I have to format to get them removed. Is this some sort of bug or is it a feature ? 
If you normally have the player set to MSC(for the USB mode in settings, system settings), try changing the USB mode to MTP, reconnecting the player, then deleting them. After you disconnect, remember to reset the USB mode on the player.
