What is the need of .ndf file ?

Can someone explain me the need of .ndf file with regards to service for which it is created.Is it enough if the xml file and the .ndf file for a service to be deployed elsewhere.

IS creates a folder in its install directory for every service as well as for an actual folder. But it identifies whether an artifact is a folder or IS service using those .ndf and .idf files. You have to deploy the service along with .ndf file. Otherwise you can not see the folders and services in the developer. Simply delete the .ndf file of a service and reload the package, you can no more see the service in the developer.
