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 button on the top bar of your media gallery. List view is a great tool for selecting multiple media items at once or reorganizing your media folders in a list format rather than in a thumbnail format.

From the list view, you can click the Gallery View button at the top of the screen to change back to the default gallery view.
