To clarify , I understand how to set these things up within individual icons, what I'd like to know is if there is a way (without using DOpus as a WB replacement) to set up Work Bench so that every time I click on a file with a certain extension and that would in turn always launch the related app. I.E. a JPG file would launch an image viewer of my choice.
Mind you, I do not want to have to edit every single icon just to make this happen.
