I have a Downloads folder where some things go. :(

Yeah, where I've got a shit load of files that, the first time, automatically download with their default name which is usually a bunch of random letters.pdf, it's quicker to just download it again than to find it!

Yes, that's exactly how the two android phones I've used have worked, and why this post is getting upvoted is a mystery to me.

There are also folders called "Camera" and "Screenshots", and I'll give you three guesses where photos and screenshots go.
