removing "stuff" from HC-2b

[faithie999]

if this info is in the HC-2 manual, I can't find it.

after a hiatus I'm back to the train room. 

I'm updating my HC-2b to ver 2.29.  I see at the bottom of the screen "Free Storage = 39%".

I assume there's stuff in the HC that I don't need.  how do I remove files?

EDIT--
never mind!  I found the "remove" page.

so now another question:
after clicking remove--pictures, several of the picture file names have CF after the name.  what are those files?

Those are files provided by customers.
