The DCE Distributed File Service (DFS) is a distributed client/server application that presents the DCE with a global view of a set of files and directories (a file system), independent of machine boundaries. This global view is called the DFS filespace.
DFS is considered distributed because files can be physically stored on many different machines, but they are available to users on every machine. DFS allows users to share files stored on computers in a network as easily as files stored on a local machine. Despite this distribution of files, it still appears to users that there is a single filespace.
