The left-hand pane of File Explorer is the Navigation Pane, which includes access to Quick Access, OneDrive, your PC, and network locations. You can easily open a folder or file from the Navigation Pane.
With File Explorer open, click a shortcut to open it.
Like other Windows apps and programs, File Explorer contains a ribbon, which is located above the file path, across the top of the app. It is composed of tabs filled with command buttons, which are grouped similarly based on function. Tabs and commands differ based on the what folder is open, what file is selection, or what function is being used. For example, the Picture Tools tab appears when a picture is selected, and the Drive Tools tab appears when a drive is selected.
