Question: Recents folder in Finder
I understand how to manage recent items in Apple>Recent Items>Clear Menu and setting the number of items listed in System Preferences>General>Recent Items but my question relates to the Recents folder in Finder. This folder contains years of documents that I've opened and that I don't want to see or tracked. Why doesn't setting preferences to 10 items keep the Recents folder in Finder to 10 items?
