Kids for the past decade plus go through school using google drive. Highly searchable. Teachers believe that kids are "tech savvy" because they know how to use tablets. So the entire process of teaching kids how to save, organize, find, and open files is gone. There are zero consequences for not knowing it either. But collages have noticed this trend for some time. Professors asking for project folders and discovering their students have no idea what they mean. It's not universal, but when the windows monopoly ended for schools, it meant kids were learning a whole different way to manage files.

Assumptions that they only know how to use a phone/tablet rather than a desktop/laptop computer, I guess. I feel like I hear most of it from their former teachers/university professors.

as long as you're aware that the file system exists at all you're probably fine, like if you really had to you could find and move shit off your phone even if the "official" file transfer thing wasn't able to find the right files
