Newbie here! i managed to download ALL of my photos into Media Twice on my Mac!

I have PSE 2020, and the Dummies book too, but Im not even up to that level.  Im a scrapbooker trying to make prints for an album of our trip to France in 2019.  This is not fun yet.  I need to start with getting rid of one set of about 15,000 photos!

Thanks, Dawn
