Yes, you’re right. I was presuming you were referencing users who know how to work with files/folders, but couldn’t describe them precisely when put on the spot. For example, I’d consider “Well, folders are containers for files and other folders. And a file is, well I don’t know, but an example is a Word document, or a jpeg.” to be a good enough description. That person is ready to roll. And I think we agree that systems designers have a bias of being able to describe and reason about their abstractions precisely, and sometimes make the fatal flaw of assuming that the end user will have this too.
