Your comment is valid about the average user. My comment made it quite clear I was not asking that category. These were not people who did not understand what files/folders where. They very clearly did.
Even the least technically competent Windows users I've known understand files and folders.
People who are primarily smartphone users - your statement is quite on point there.
Those people likely barely understood many concepts. I’d never think to seriously go to an Apple centric bigger forums. Unless it’s specifically geeky and into being able to manage things with automation, scripting, CLI, power apps, etc, Apple communities generally give very little and weak info.
Those pseudo power Apple Mac users are not that far from average users.
