Essentially what I want, is a vertical file display (one left and one right), and above the file display will be a toolbar which contains two location bars (path, breadcrumbs, favourites etc...) above each file display.
Changing the location in the left location field will be represented in the left file display, and the right location field will update the right file display.
A little like the screenshot, notice the left file display is C:\Program Files, but the location bar says C:\Windows
Enter customize mode (Settings -> Customize) and then right-click one of the location bars and choose Edit. In the window that appears, type either left or right into the Args field.
(You can also type dest to bind the field to the destination file display.)
If there is already something in the Args field, separate additional arguments with commas. e.g. driveroot,left
