iOS 13 makes it very easy to create and work with a two pane file manager similar to Norton Commander or Total Commander.
I started with a single window of Files. Then I dragged the Desktop folder on the right to the left part of the screen. That’s it. No need for a special KM macro or messing with creating a second finder window, then using the screen dot.
