Using cli interface to open / reset opus

Are there cli parameters that I can use to open a new opus or use the last opened existing opus to display the contents of a folder and select a specific filename?

I have a ScanSnap scanner that I use to convert docs to pdfs and store them in a specific directory. Currently I have the program setup to launch opus and it displays the new pdf in the default view. When I scan several documents, I get a separate opus window for each one. I would like to be able to specify the type of opus view ( image, explorer, etc...) and open a new opus window if none are currently active or reuse the last currently open one.

Is there a way using a script or combination of cli arguments to do this?
Any help or examples would be great.

Thanks
Mark

You can use dopusrt.exe to run Opus commands from external batch files.

This could go to my Desktop folder and select the Opus.txt file:

"C:\Program Files\GPSoftware\Directory Opus\dopusrt.exe" /cmd go "C:\Documents and Settings\Leo\Desktop\Opus.txt"

(Should be all on one line.)

A command of Prefs STYLE=Commander would set the active lister to the Commander style:

"C:\Program Files\GPSoftware\Directory Opus\dopusrt.exe" /cmd Prefs STYLE=Commander

The Go command takes care of your wish to re-use an existing window if there is one, and open a new one if there isn't, automatically. The only thing I can't see how to do right now is how to make the old window come to the front.
