The file tree can display the label or name of the file(s) and the contents of the applications currently open. To toggle between labels and names in trees, open the View menu select Names in Trees, or press Ctrl+T. A check mark appears next to the Names in Trees menu item when names are displayed instead of labels. The setting affects all the trees.
If you would like to view both the name and the label for each item in the tree, select the Append Labels to Names in Tree option.
To toggle between trees on left (i.e., split screen) and full screen, open the View menu and select Full Screen, or press Ctrl+J. A check mark appears next to the Full Screen menu item when the display is in full screen mode. This setting affects all applications.
