keep getting error when trying to deleat anything

[Tfast500]

i just got in my xv6800 today and put in my memmory card and was playing around.

I have a bunch of pics and videos on my card and on the xv6800 itself and everytime i try to delete them i get an error saying:

Cannot delete:
'xxxblablahxxx': Access is denied.

Be certain that the file is
not write-protected
and is not currently in use.
