I needed to be able to retrieve the folder currently being explored by an instance of Windows Explorer. To that end, I had to write a function to do this which I've copied out below. Feel free to re-use this if you find it useful.
#include-once

; <_GetWindowsExplorerPath.au3>

; _GetWindowsExplorerPaths()
