I am wanting to copy a large number of files from my laptop to an external hard disk. About 70 GBs to be precise. I'm just using copy + paste commands in windows. If you leave it going overnight, in the morning you can be disappointed when you see that it has stuck on a message like "do you wish to overwrite this file" with 30 GBs of files still to copy. Is there anyway to move the files without any messages. Any advice or backup software recommended would be appreciated.
