PhotoDirector 365 is the easiest and quickest way to manage photos. First, automatically sort your images by years. Then, create subfolders within each year. You can do this by event (Christmas, Birthdays, Dance Recitals, etc.), by people (i.e. creating a folder for each of your children), by month, or by any category that you will find useful.
Once each year has the necessary subfolders, you can start going through and deleting duplicates and comparing similar images. You may want to save only the best of each similar group or assign a star rating or flag to the best of the bunch. You may want to create a separate album of the very best photos from each year. You can also apply tags that will help narrow searches so you can find images easily.
