It is a small disk read from a dvd/cdrom reader. It came with an "IP camera" just delivered. I would like to save it to my NFS server but it does not put anything on the sever although it appears to go through the process of making the copy, when I read it from NFS there is no file there.

Copied to the Desktop it the .pdf does not display, Thunar protests it is a "broken link."
