She's right

This is an interesting glitch.

I think I know why - back in the old DOS days, when I was a wet-behind-the-ears computer lab assistant, you could make new files by typing "copy con whatever.txt" at the A:\ prompt. That meant take input from the console (aka the keyboard) as long as the person wants to type and then when they tell you they're done, save the file as "whatever.txt"

So, no folders named con. It's a reserved word.

I could be wrong though. ^-^
