There does not seem to be a facility to delete a file once it is uploaded to the "Files" section. Maybe this
is just a permissions thing with the guest account on the demo??

As it's said on the demo welcome page, the "guest"
account has limited rights on the sandbox project.
The functionality for deleting files is of course available when
having the right permissions.
