This ObjectType defines a type for the representation of file directories. It is formally defined in Table 8.
It is expected that OPC UA Servers will create vendor-specific subtypes of the FileDirectoryType with additional functionalities like Methods for creating symbolic links or setting access permissions. OPC UA Clients providing specialized file transfer user interfaces should be prepared to expose such additional Methods to the user.
