I only learned about these when I was trying to scrape information about airports and save each in their own folder named after their IATA code. I learned about NUL, PRN and CON because of Nulato Airport, Pristina International Airport and Concord Municipal Airport.
Such a weird bug, I didn't know why I was getting a FileNotFoundError from trying to create a new file. Everything online will tell you the directory you're placing it in doesn't exist (it did of course), and no hint that you're trying to use a magic name.
