In either the Tree view or the List view, you can set the root location of the view.
To set the root of the current view:
In either view, select View>Set Root from the menu bar, or select Set Root from the pop-up menu.
If you want the root to be a directory or library, type the path or browse to the path.
If you set the root to the Library List in both the Tree view and the List view, only the name of the current library displays in the Tree view and only the objects in the current library display in the List view.
