It's not. It's a reserved word through the MS-DOS file redirection facilities. If you use the newer file API or you use the \\?\[path] convention; the reserved words are not an issue and you can create files named for them.

You have to use both, actually. The Unicode API and the \\?\ path prefix. It also astonishes me sometimes how many applications nowadays still choke on Unicode paths.
