How to Download Your Information from Facebook
One feature strangely absent from Facebook has always been the ability to download your pictures, videos, messages, and other information to your hard drive. Now, with a few clicks, your updates can be easily saved.
All you need to do is head to Account, Account Settings, then to Download Your Information. From there, you can download a zip file containing all your profile information, including your photos, wall posts, messages, videos, friend lists, and other content. If you unzip the file, you can actually view a simple HTML page of your profile, with simple links to all of these things. It doesn't look like there's currently any way to re-import that information back to Facebook.
