Reparse Points Solve Path Problems

We have a program at work that manages users' profiles. This program had been developed to work under Windows NT 4.0, whereas we needed it to run under Windows 2000. When we tried to use it with Win2K, we ran into a problem: The program was hard-coded to use the C:\Winnt\Profiles path and offered no way to configure it to use the C:\Documents and Settings path. Unfortunately, the original developer had left the job, and there was no source code for this program.

After searching the folder in which I keep all my administrative tools and utilities, I found the right tool for the job: Sysinternals' Junction (
ntw2k/source/misc.shtml). This command-line program creates reparse points to NTFS-formatted hard disks. You first create the folder you want to appear as the "real" one (C:\Winnt\Profiles, in my case), then run Junction following the syntax

junction <your real folder>
  <the fake folder>

In my case, the command was

junction "c:\documents and settings"

Now, the C:\Winnt\Profiles folder points to C:\Documents and Settings.

It's important to understand that your files don't replicate. Junction just creates a pointer. So, every change you make to either folder is actually reflected in the other folder as well.
