By default, all files are displayed in the Gallery view on your Home page.  To see files displayed in a List view, click the List View icon on the top User’s Menu bar. List View is a great tool for selecting multiple media items at once or reorganizing how you view your media in a “List Format” rather than in a thumbnail format.

From the List View, you can click the Gallery View link at the top of the screen to change back to the default view.
