The following commands can be called to manipulate file system junctions:
Each command is wrapped with either the nssRequest or nssReply element and the junction element.
A junction is a special type of file that is used in Distributed File System (DFS).
To a client that is DFS-aware, a junction appears as a directory. The directory contains the entire volume subtree to which the junction points.
To a non-DFS-aware client, a junction appears as a file that cannot be opened, modified, or deleted.
