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 simply shows you recently opened documents, regardless of where they are located. 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. I’m partial to Desktop or Documents, but you can choose whatever folder makes sense with your workflow.
