You can't :-)
Well, thats not strictly true. But C:\Users\All Users is not actually a
directory; it's a "symbolic link" or symlink. This is like a soft link in
Unix. They existed to some extent in Windows 2000, XP and Server 2003; but
most users never encountered them; only server administrators and the like.
But Vista uses symlinks much more widely than previous versions.
On a Vista machine you can see where the symlink points to by using a "dir
/a:s" command; eg:
C:\Users>dir /a:s
Volume in drive C is System
Volume Serial Number is 7846-1538
Directory of C:\Users
03/11/2006 01:41 <SYMLINKD> All Users [C:\ProgramData]
03/11/2006 01:41 <JUNCTION> Default User [C:\Users\Default]
03/11/2006 01:27 174 desktop.ini
1 File(s) 174 bytes
2 Dir(s) 19,171,004,416 bytes free
C:\Users>
So, "C:\Users\All Users" is actually a symlink to the "real" file system
direectory, C:\ProgramData.
On Vista, you manipulate symlinks using the mklink command. Windows XP has
no built-in comands to manipulate (delete, create) symlinks. You can delete
it using the Junction.exe utility, a small, free download from Microsoft:
http://www.microsoft.com/technet/sysinternals/Utilities/Junction.mspx
Download it to your XP machine. Then run the command:
C:\>junction -d "C:\Users\All Users" C:\ProgramData
(it shouldn't matter that C:\ProgramData doesn't exist any more).
Hope this helps,
