When you’re in the Finder, choosing File > New Finder Window does as you’d expect open a new Finder window. But what folder appears in that window? By default, new Finder windows open to Recents which is a built-in smart folder showing recently opened documents.
If you’d prefer to see items in a fixed location on your drive, go to Finder > Preferences > General and choose any location from the New Finder Windows Show pop-up menu. We’re partial to Desktop or Documents but you can choose whatever folder makes sense with your workflow.
