Dropbox is awesome. It’s a service that runs on your computer and at its simplest copies anything you put in your Dropbox folder out to their server and any computer that is connected to your Dropbox account. You can pay a fee for additional space and features. But the basics are free and available on Macs, Windows and Linux. Yay!
