In Windows (including XP), certain names like 'con', 'prn', 'aux', 'nul' are reserved device names dating back to MS-DOS for compatibility - 'con' was the console device. These reserved names cannot be used for files or folders. Attempting to create a folder named 'con' will result in an error. Therefore, the answer is False. Note: The question has grammar issues ('window' should be 'Windows').
