I wanted to free up space on my Macbook Pro and delete photos / movies. I have successfully backed up / copied the libraries to an enternal hard drive (and confirmed everything is there). When I looked up deleting photos, I came across postings that FB photos would be deleted, too. Is there a way to "find" FB photos (mine are included in several "events") so I can put them in separate "event" for now (and future) and then delete the rest?
