Directories

An application cannot create a directory with CreateFile; it must call CreateDirectory or CreateDirectoryEx to create a directory. Opening a directory with CreateFile requires the FILE_FLAG_BACKUP_SEMANTICS flag.

FILE_FLAG_BACKUP_SEMANTICS Indicates that the file is being opened or created for a backup or restore operation. The system ensures that the calling process overrides file security checks, provided it has the SE_BACKUP_NAME and SE_RESTORE_NAME privileges. For more information, see Changing Privileges in a Token. 
You can also set this flag to obtain a handle to a directory. Where indicated, a directory handle can be passed to some functions in place of a file handle. 

Windows Me/98/95:  This flag is not supported.
