By default, the Nautilus
file manager uses
the default font settings that are specified in the Font
preference tool to display the text in the file manager window. However, you
can further customize the font that is used in the file manager view pane.
To customize the font that is used in the view pane, click on the View menu in the file manager, then select one of the following
menu items:
To enlarge the text, select Zoom In.
To reduce the text, select Zoom Out.
To reset the text to the default font setting, select Normal Size.
