Can I delete?

[OB1J3D1]

All,

I was wondering what some of the stuff on my SD is.

Can I safely delete:
the kindle folder if I don't use kindle
my_music folder
myalbum folder

What are the my_music folder and myalbum folders for?

When I drag and drop music onto my SD, should I be using the my_music folder? OR should I create a new music folder?

Thanks much in advance
