I still use folders to organize paper documents. Taxes and medical stuff mostly.

I agree. I heard recently a lot of kids under 20 grew up in an iPhone, iPad, and chrome world and never learned “folder” or directory concepts so it’s a tough transition in the work world. Paper organizers are not nearly as ubiquitous as they once were.

It connects it to another computer symbol, the folder which is seen plenty of times as the thing containing files. It's a solid solution.
