I've continuously upgraded my Quicken since 1989, and have retained every account. I now have about 40 defunct accounts, and only three active accounts I want to keep — 2 checking, 1 credit card. Current .QDF file is over 24,690 KB — very unwieldy, sometimes won't load at all. How can I streamline my .QDF, keeping only my 3 active accounts? And in those 3 accounts, I'd like to purge thousands of entries from before 2015. How do I proceed?
