Tapping a subfolder reveals thumbnail images of files in that folder. Swiping upward from the bottom of the touchscreen or right-clicking reveals file and folder options: Feedback, Refresh, Add, Details, and Select all. Feedback lets you tell Microsoft what you like or dislike about the app. Refresh updates the view of the current folder. Add lets you upload more files to SkyDrive. Details switches from the default large thumbnail view to a smaller thumbnail view with more information about each folder or file. Select All selects all of the files in the current folder and displays three more options: Clear, Save local, and Manage (delete).
