Change Appearance Of Navigation Pane. OldNewExplorer also allows you to change the appearance of the options bar above the file list and the Details pane. Go to the View tab and click on Navigation Pane option.
Slowly but surely the navigation pane began to fill. You might notice that the Folder pane drop-down options include more than just turning Favorites on and off. Right-click any empty space in the navigation pane and click Show All Folders to see this option.
Then you need to find a Grid named TopNavGrid in the ControlTemplate.
Being able to resize the Navigation Pane would do much to solve these issues as it uses far more room than it needs in most scenarios for our users. Right-click any empty space in the navigation pane and click Show All Folders to see this option. Click outside the name and then click save. This arrow is also available in the Navigation Pane header in other views such as Contacts and Calendar.
