I'm trying to find where to increase the font size of the Navigation

where to increase the navigation pane font.

The font size of the folders in the Navigation Pane is controlled by your
Windows display settings. Right-click the desktop, choose Properties,
select the Appearance tab, and choose a font size in the "Font size"
drop-down.
