As a technical person, who only ever used Android, I have no idea how files really work on my phone. I even used adb a few times but still. From my PoV there are no "files", just photos, videos, screenshots, downloads, application data, applications and system data - all completely different kinds of data.

In my files app i see "downloads" "images", "videos", "apps", "starred", "safe folder". In "images" i see pictures tagged "downloads", "camera", "DCIM", "screenshots" and one odd "2024-12-03_description_here" that I clearly names myself but don't remember doing that.

I have no clue how that maps to a physical phone filesystem, even though I know it's there. I'm sure teenagers don't know that too.
