Microsoft Windows Naming System for Folders

More articles by »
Written by: arunenigma


In windows the folder name and the special system variables share the same interface, so when you create a folder with a system variable name it will consider that folder already exist. These special system variables are available irrespective of path.

You cannot create a folder with these names also:

CON, NUL, COM1, COM2, COM3, LPT1, LPT2, LPT3,COM1 to COM9 and LPT1 to LPT9….

CON means console, COM1 means serial port 1, LPT1 means parallel port 1.
