How delete non-user songs loaded to dgx 660-

[MiddleC]

Early in my learning curve on my dgx660, I loaded some songs into the keyboard which are not user one through user 5.

For example I have one that I had created and saved out to my USB called midi Time to say goodbye. Of course it's a midi file and I can play it.

No I'm realizing it's taking up space in there that I probably should not. Probably on alarm is user one through user 5 whenever I want to play them.

Is there any way to delete that song, and of course a few others I've done this with?

Never mind, I actually checked the instructions and found that I can do it with the file control without the USB even being installed.
