About a year ago I had to replace my laptop, and I never switched out the hard drives. So I want to get all my old files off of my hard drive and onto my new laptop. All I have existing of the old laptop is the hard drive itself. Both laptops ran on Windows 7, but my old laptop was an Asus and my current laptop is a Dell. (Not sure if that matters or not.) How can I get all of my old files onto my current hard drive?
