Cannot create a specific file named “con.php” in Windows

Question

I have Windows XP SP3 and cannot create the file named con.php anywhere on disk. I get a message that the file already exists.

Searching in Windows explorer I found not one such a file name on the whole disk.

Why is this happening?

Answer 1

Con is a restricted filename in Windows, so you can't name any file or folder "con". This link provides more info, as well as a utility that (apparently) lets you get around this restriction: http://www.thewindowsclub.com/create-restricted-files-folders-con-aux-nul-click-windows
