Hi,
I want to do a similar thing, but did not find a way to do it using only Macro Express (I'm using Pro). I'm running XP and use this utility "Copy File Path and Name using Windows Explorer Context Menu Extensions" (http://www.gnostice.com/nl_article.asp?id=168) to get the file or folder path to the clipboard using the right click context menu. I then use an ME hotkey to run my macro that sets this path to a string variable from the clipboard. I hope this helps. Or maybe you discovered by now a way to do this using only ME?
Mike
