As a dos/windows/linux users my whole life, I got asked by some family a few years back to get photos off of a mac from a deceased family member. I pulled off everything I could find, but I was never sure I actually found everything because I basically had to just search for different image types, but had no real way to browse to actual folders where things were stored.

It's a Unix system under the fancy UI. Of course there are folders and of course you can go to them. You can also grep in the terminal or whatever you are used to do from Linux to your heart's content.

Personally, I think the representation of the directory tree in Linux and MacOS is equally jarring for a person who has grown up with DOS and Windows. It certainly was for me when I peeked my head out of Bill-Gates-Land as a teenager.
