Dunno, that's what high school level computer courses are for. I was in high school in the early 00's and they taught us stuff like Word, Excel, HTML, basic computer literacy stuff like filesystems, how to touch type, etc... And that was a required course in a public high school...
Computer classes in HS don't really cover that anymore. It gets worse the less relevant file systems are to non-techies. Documents are just a thing search for these days. People also learn and retain learning of what they practice, you would have to get them to use file systems, and then get them to continue using file systems for that information to stick.
That's kind of crazy. Basic knowledge of at least one desktop OS and office suite is kind of a prerequisite to so many things that would be considered adult life...
Like, are kids writing CVs on their phones? Writing essays on their phones? iPads? Paper?
