In a terminal, look in /run/user/<userid>/gvfs to see if the mount

mount
point for "gvfsd-fuse".
Thanks Samuel, I found the mount point where you said it was and
successfully copied the files in a terminal window.
Pity that Files (the Gnome application) can't copy large files and that
it doesn't give the user information about the mount point.
