Hi, my name is James Flint, I'm going to show you how you can copy your entire iTunes music library from one computer to another. The way I would choose to do this is to copy your iTunes music folder to an external hard drive, and then connect that external hard drive to a new computer and copy them back over. So first you got to install or hook up your external hard drive. And I've already got that done, so we're going to go into our system hard drive in our music folder we've got iTunes, iTunes music. So what you would do, first you need to make sure that you have enough room on your hard drive to copy your entire iTunes music library. My iTunes music library is about ten gigs worth of music and my hard drive has five hundred and ten gigs available. So we've got plenty of room. So all you need to do is select the folder iTunes music and pull it over to your external hard drive, and the copying begins. Well now that you've copied your entire iTunes library to an external hard drive, you can begin importing the songs back onto the new computer, the second computer. So what you'll do is on the computer that you want to copy these files to, you can go to iTunes and again - I've already hooked the hard drive up to this new computer, so we will go to the files menu, and then add to library, and then from here, you find your external hard drive, find the iTunes music folder, and then simply say choose. And now it's going to start copying everything over, and that is the essential step for copying these files from the hard drive to the new computer.
