A '''directory file''' is a file containing a listing of a directory in [[Files-11]] directory structure. It always has the [[File extension|extension]] of .DIR and [[Version|version]] 1. With the exception of 000000.DIR;1, directory files are located in the parent directory. Directory files are created automatically when a directory is created with the CREATE/DIRECTORY command.

To check whether a file is a directory file, use F$FILE_ATTRIBUTES(filename,"DIRECTORY") - this returns true if filename is a directory file.
