I am the administrator and only user of my laptop with a new installation of 14.04. I created a bootable USB and when it is used I find this file "PRJ_20071023" that I can not read or delete. I get a message that I do not have permission to access or delete the file. How can I get around this limitation. Although I have an administrator account, I appear to have no administrator rights.
Any help you can offer will be greatly appreciated.
