I always thought of this as: Notepad is an app for viewing and editing text files, which contain characters. It lets you delete, change, and move/copy existing characters, and also add (type) new characters. Explorer (like other file managers) is an app for viewing and editing folders, which contain files. So it makes sense that besides deleting, changing, and moving/copying existing files, it also lets you add (create) new files. Maybe not literally true, but a nice mental model to entertain for a few moments’ entertainment! (It also suggests it should be possible to take this a lot further than Windows and Explorer do; does anyone know of any historical or current file managers that do a particularly good or interesting job here?)
