At least in Internet Explorer 3 and Netscape Navigator, cookies were stored as individual files in the file system. In that sense at some point in time it was somewhat correct.

However the relevant part: On e in a time computer users knew files and we're working a lot with them. Operating systems like Windows 95 pushed files into the front (instead of first picking the program and in the program opening the thing they pushed Explorer to "explore the computer" and then finding the right program for the file) There a file was a understandable unit of data.
