Cannot create Windows folder con?Here is the reason

Posted on: June 27, 2007

It was discovered that nobody can create a folder named as “con”(also com1,lpt1, in windows.
This is something pretty cool…
we cant create a folder named CON, NUL, COM1, COM2, COM3, LPT1, LPT2, LPT3,COM1 to COM9 and LPT1 to LPT9….in any of the windows operating system because folder named con and others are system variables.

HINT for search: recall the old MS Dos “Copy con” command, and COM1 etc are port names…
