Scott Hanselman has a great post on junctions in Windows Vista. Scott mentioned that he was seeing different behavior from David Mohundro surrounding the Documents and Settings folder. I ran my own tests and this is what I came up with.
C:\>dir /ad
Volume in drive C has no label.
Volume Serial Number is 6053-B050Directory of C:\

So I’m seeing “C:\Documents and Settings” as a junction pointing to the new C:\Users. Makes Sense, but a directory listing on Documents and Settings didn’t return anything.
C:\Documents and Settings>dir /a
Volume in drive C has no label.
Volume Serial Number is 6053-B050Directory of C:\Documents and Settings
File Not Found
However, I was able to change to “C:\Documents and Settings\rob”, and it behaved as expected, showing the same contents as C:\Users\rob. Looking further, when I double click Documents and Settings in explorer I get an “Access denied” message. Looking at the folder permissions gave the answer, Documents and Settings has a special permission setting of Deny Everyone for “List folder / read data”.
