...ok, one more followup, since I looked at the walkthrough to see where I got stuck.
Re "Archive's Desktop": I certainly saw the word when I zoomed in on the photo. It wasn't clear to me, though, that that was different than the actual wallpaper; I thought it was just clearer, and said, oh, ok, now I know what the wallpaper says. So it didn't totally stand out as important.
Given that, though: I did have the word, but it wouldn't have occurred to me to use it as a password for one of the locked folders. It might just be a difference in perspective--maybe other people have more of a "when I find a potential password, I'll try it everywhere" approach. I was looking for something that would tie what I found to the place I needed to use it.
Different people like different things though. Hope this finds its audience!
