Files has been around for years as one of the earliest Facebook apps. It was always intended to be handy, not profitable.
Now we're redesigning the service to allow you to more easily share and sell your files. During this retooling, the app will not be available.
Come mid-May, we'll be back with a new website, and new iPhone app (Android to follow). Get ready to share everything you make, and to make money on everything you share!
