Have you ever had the situation where you are flipping between drawings (in SDI 0) and find that when you go to "Open" another drawing the file selector is displaying the wrong directory?
Here is a neet little macro/script to put in a toolbar button to open Windows Explorer into the currently displayed drawings directory.
^C^C(startapp "explorer" (strcat "/e, "(chr 34)(getvar "dwgprefix")(chr 34)))
