Scientist here, a lot of my job is writing texts with references to other literature of the field, or reviewing such texts (or PowerPoints). Main screen has the document open, the other is actually in portrait format and has gazillions of open pdfs on it that are relevant to whatever I’m working on. I had to get this setup for working from home because productivity dropped immensely with only one screen.
I guess it shows how out of touch (old) I am that it’s completely bewildering to me that there could be people who do not understand folders … on a computer. Phones, tablets, yeah, I get that, those actively make it harder and harder to access the folder structure. But computers?
