Congratulations! You got a new computer. If it’s your work computer, your IT department probably installed all the business applications you need on it. But it doesn’t have any of your files on it; those are still on your old computer. So you’ve rolled up your sleeves and are preparing to spend a lot of time and effort moving your files from your old computer to your new one.
Stop! There’s a better way, at least most of the time, and it works whether your old and new computers are Windows PCs, Macs, or a combination of both.
