Dealing with files used to be something everyone interacting with computers had to do. It is something average people can do.
I think too much abstraction is a mistake and adds a lot of unneeded complexity.
People should learn something about technology they use. If you want to drive, you need understand how steering wheels work, if you want to drive a manual car (usual where I live and have lived) then you need to know how to work a gear stick and the effect of changing gear.
I'm not even sure 'everyone with an office job' had a computer. It certainly wasn't true 35 years ago. An office might have a computer or two, but not everyone had one, nor was everyone expected to use it.
