George would like to know the best way to transfer his files from his old Windows XP computer to his Windows 7 system. Leo says that Microsoft has a files transfer program built into Windows that does a fairly good job. But this is a great opportunity for George to make a backup. He should go and buy a USB external hard drive, and backup everything in his Documents folder. The advantage to this is that he'll have a backup on a separate drive while transferring his files over to the computer.
