DOpus documentation states: "The search field on the Menu toolbar lets you access the Windows Search system from within Opus." I customized DOpus years ago, and cannot find any "search field" or how to access it.
"Find Files" results do not show the folder in which files found are located in. Is there some way to fix this, such as to customize the columns shown for search results?
If you want to add the Search Field to your custom toolbars, go to Settings > Customize Toolbars > Commands, type search into the field at the bottom left to narrow things down, then drag the Search Field item to somewhere on your toolbars:
If your Find Results collections aren't showing where things are, you can add the Location column to them. Editing Preferences / Folders / Folder Formats / Folder Type Formats / Collection is usually the way to go, but also check in the Path Formats section of the list in case you have any formats saved for specific collections like coll://Find Results which would override that.
