Phones are aggressively hostile to any file management. Many apps just straight up don’t give control of actual directories to end users. Manually modifying the directories of software at all is effectively hidden under an exploit and outside legacy ported software it is hard to meaningfully change anything even that way.

So I would not blame youngsters that don’t have personal computers. Mobile OS obscure the use and neuter the potential of learning the file system, there are massive hurdles for fringe benefits, completely different from especially PC use in our time where this was fundamental knowledge and enabled doing all kinds of interesting and useful stuff.
