Thank you for this reminder. I think we either assume people do not need to know about files structures and therefore do not teach it OR we assume they must already know it to be at the level they are but they do not.
Meanwhile "we" are all self-taught. No one ever taught me about files. This would first come up in Hardware near then end, but I don't think that makes it "real" Maybe Networks should be "Networks and Files Structures"
What would be an awesome memorable lesson? hmm
