I just downloaded an Ubuntu 12.10 iso to update my operating system. But when I copy this file to the usb(h:/), it doesn't work. The copy one in the USB is "0kb".
It make me feel awful, if the size is limited? When the file is too big(700mb and more), it may doesn't work? I am a newer, hope you answer. Many thanks.
ps:you also can give me a email (mine is :email@example.com)
