Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed.

The NFS client aims to make transparent remote access to the user's computer, and this interface client and server, run through the NFS client-server protocols, is well defined when the user to call a file / directory on the server, you seems to be accessing locally, and is working with remote files.

For customers to access the files, there is a request to the server, depending on the permissions of the client, responds confirming the request. From this point on the hierarchy of directories and remote file becomes part of the local file system of the machine.
