OK... first look and read here.. [URL]http://wiki.jriver.com/index.php/The_Command_Line[/URL] From what I read there your above example is not even close Try figuring it out... looks rather straight forward. Replace the mc16.exe with mc18.exe and where you see "C:\path\to\file.mp3" in the examples replace it with "%1" OCD will replace the %1 with the path and name of the song that you selected. So.. give it shot and let us know if you get it working.. or not fred
