I'm saying that your reasoning about the problem is stuck on outdated metaphors, and your imagination may be irrevokably damaged. You are asking the wrong questions, and so the only possible answer is "mu"
https://en.wikipedia.org/wiki/Mu_(negative)Let me put this another way- Having to work with files is a problem which is caused by computers. It is not a problem that existed before computers which is now solved by them. There are LOTS of alternative metaphors that have been tried and written about and researched before which you can simply just go find out about if you ever decide to look into it. The reason none of these alternatives have been adopted widely is because the file system metaphore has just simply been too ingrained. iOS is now the first system that has half a chance of shedding the metaphor once and for all, and people whose minds have been damaged by experience with file systems now simply want to add it back in. What a tragedy.
Okay here's a freebee. Have you ever been working on a large paper, and you forget to "save" your "file", and your computer crashes and you lose your work? That is a clue to the problems with this metaphor.
