Maybe you got a Kindle Fire and aren’t that crazy about it. You want to sell the thing, give it away or return it to Amazon or the store where you bought it. It could be you just want to start over and remove all the free Amazon App Store of the day apps, documents and junk and go back to factory default settings.

You’re looking at the built-in SD card and all of your documents, books and other personal files.
