So I was driving myself wacky why my folder wouldnt allow itself to be renamed “Con”. Apparently there are a few keywords that cant be used as folder names on Windows, Con being one of them. Others include:  
AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL

Thats all new to me. Pffft.

So here’s a heads up, dont name your files/folders any of the above names 😉
