some files suddenly inaccessible

[Susan]

Hi! I am a newbie who received a 3.8 GB Delstar as a Christmas gift. Now I know what so many love these things! I have loaded many songs on it, and last night I experimented with folders. I ended up with a bunch of songs not in a named folder and two named folders. I noticed at the time that I had used only about 361 MB of the player. This morning it played in my car perfectly. I was able to move from the main music group to folder one to folder two without any problem. I was listening to stuff in folder two, then I arrived at the store and I turned off the car as usual. When I got back in my car and turned on the music again, all it would access was folder one and a single song which it said was in folder two (but it hadn't been) and nothing else. I got home and hooked it up to my computer. The Explorer only shows folder one with about 40 MB of stuff, and that single song which is about 3 MB, but it says that the player is using about 361 MB of memory.

So, the music is still there, but I can't get to it.

Any suggestions, please?

Thank you -
Susan
