Junction v1.04

By Mark Russinovich

Introduction

Windows 2000 and higher supports directory symbolic links, where a directory serves as a symbolic link to another directory on the computer. For example, if the directory D:\SYMLINK specified C:\WINNT\SYSTEM32 as its target, then an application accessing D:\SYMLINK\DRIVERS would in reality be accessing C:\WINNT\SYSTEM32\DRIVERS. Directory symbolic links are known as NTFS junctions in Windows. Unfortunately, Windows comes with no tools for creating junctions - you have to purchase the Win2K Resource Kit, which comes with the linkd program for creating junctions. I therefore decided to write my own junction-creating tool: Junction. Junction not only allows you to create NTFS junctions, it allows you to see if files or directories are actually reparse points. Reparse points are the mechanism on which NTFS junctions are based, and they are used by Windows’ Remote Storage Service (RSS), as well as volume mount points.

Please read this Microsoft KB article for tips on using junctions.

Note that Windows does not support junctions to directories on remote shares.

If you want to view reparse information, the usage for Junction is the following:

Usage: junction [-s] 

-s  Recurse subdirectories. 

If you want to create or delete a junction, use Junction like this:

Usage: junction [-d]  []

To delete a junction specify the -d switch and the junction name.
