You can use the Shell.Application object to get a handle on a running instance of Explorer:

oShell = CREATEOBJECT("Shell.Application")
FOR EACH oWindow IN oShell.Windows
	?oWindow.LocationURL
	IF oWindow.LocationURL = "file"
		oWindow.Navigate("file:///C:/Data")
		EXIT
	ENDIF
ENDFOR

The Windows collection contains both IE and Windows Explorer instances, but you can tell which are which by looking at the LocationURL property

Once you decide which instance you want to use, just use the navigate method to change its current directory. If there are no open instances, you can use the Shell.Explore() method to open one:

oShell.Explore("c:\data\")
