[9] Directory junctions (which can be created with the command MKLINK /J junctionName targetDirectory and removed with RMDIR junctionName from a console prompt) are persistent, and resolved on the server side as they share the same security realm of the local system or domain on which the parent volume is mounted and the same security settings ...
Support for directory and UNC paths were added in NTFS 3.1. NTFS volume mount points; All NTFS links are intended to be transparent to applications. This means that the application accessing a link will be seamlessly redirected by the file system driver, and no special handling is needed. To users, they appear as normal directories or files.
