Simple, get a FREE Dropbox account or other online cloud account. Dropbox is software that syncs your files online and across your computers. Save your files into your Dropbox folder on one computer, and they'll automatically appear on any of your other computers that also have Dropbox installed (Windows, Mac, and Linux too!). You get 2GB storage space for free and you can access your saved files from any computer anywhere in the world. Alternatively just email yourself the files.
