How can I tell what version I have?
How can I search this forum so I will not ask a question that has been answered earlier?
I think one version allows three panes instead of the current two. If I'm correct, which version?
Thanks, Jim
Within the program, Help > About Directory Opus will tell you which version you have installed.
According to your account on the forum, you own Opus 11 Pro. (Opus 11 licences work with Opus 10, so you may still have an older version installed. If you have purchased Opus using multiple separate accounts, the forum only knows about the one linked to your forum account. Most people only use one, though.)
Click on the magnifying glass icon near the top right of the page.
You've can't have more than two file displays visible at the same time in a single window.
But you can have multiple windows side by side, with one or two file displays per window, and save them as a Layout which can then be recreated by loading the layout whenever you need it.
Folder tabs also let you have more than two file displays per window, but not all visible at once.
