There’s something i bet you never noticed. It is impossible to name a folder “con” on any Windows Operating System. Try if you like, you can try anything from creating a folder in a folder, to compressing a file into a new folder. You just can’t do it. Personally, I feel the title is being reserved, mainly because of the old MS DOS, Console, but this is more useful to the more computer skilled people out there.

So, in conclusion, you can’t call a folder “Con” because Microsoft won’t let you. That’s pretty much it.
