The File Browser allows you to browse your entire file system from the app. You can launch programs as well as open movies, pictures, ect. To use it, go to the application switcher and tap the folder icon (the last icon in the list). There are buttons along the bottom that will take you to your Computer, Documents, Applications, Desktop, as well as the ability to create favorites from whatever directory you are currently in. To launch a file, just tap it. To open the folder of the folder in the list, or the folder containing a file, just hold your finger on that item until it opens. To change the sort options, scroll up to the top and you can sort by date and change to ascending or descending order.
