Instead of saving files to a USB flash drive, emailing yourself attachments, and worrying about which version of a document is the most up to date, store all your files safely and securely in a DropBox. DropBox is free cloud-based storage, meaning your files are stored somewhere safe from breaking and crashing computers.
What 'cloud storage' actually means to real people: You can access your files from basically any computer and device - iPad, laptop, smart phone, whatever, from anywhere. DropBox installs a small program on your computer and creates a folder called DropBox on your computer. Just start saving files to that folder, and all your other computers or devices automatically update files as you add or change them. You get 2GB of storage for free - So don't upload your entire photo album right away. Your computer will crash, get dropped, be driven over, or fall in a muddy pasture at some point, so save your files 'in the clouds' to keep from losing them. DropBox stores your files on Amazon.com's servers, which claim to be safer than any bank.
