I erased the USB drive this way:
SETTINGS -> Device Info -> Reset Options -> Erase USB Drive
After that, all my videos/pictures were deleted... even the default Touchpad wallpapers
were wiped out.

appeared out of nowhere. I cannot figure out where it came from . I certainly didn't
put it there. Does anyone have any idea where it might have come from?
Here is a screeshot of my Touchpad right now:
