Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I've researched a bit and came to the understanding that VirtualStore is part of the new UAC feature in Vista/W7 which is the file system part of the transparent data redirection and redirects write access to folders like program files to C:\User\<username>\AppData\Local\VirtualStore\ in lack of applications respecting the LUA principles.

Now I'm interested if that kind of transparent redirection can also be used as a power to the user. Here's an example which comes to my mind:

I install any kind of software to e.g. D:\Whatever\ThisAndThisApp\ and I set up things that, after initial installation, any write access to this folder is transparently redirected to e.g. D:\MyOwnVirtualStore\Whatever\ThisAndThisApp\file_only_writable_here.txt.

Is this thinking too far or can I actually use that power of VirtualStore as a user on Windows 7? I'm using the Professional version zf that matters.

As far as I know you can't, and in any case the Virtual Store is hardwired to be the folder
C:\Users\username\AppData\Local\VirtualStore.

The only mechanism available to users are Symbolic links, which under Windows 7 are known as Hard Links and Junctions.

If that's something you would like to use, you will find the program Hard Link Magic to be useful.

Symbolic links are soft lonks and are different to hard links. Windows 7 includes the mklink tool to handle links. Junctions are effectively symbolic links which point to a directory rather than a file. As mklink allows one to make symbolic links to a directory they seem rather pointless. –  Neal May 30 '10 at 20:14
    
Accepting, as it seems what I'm asking for is currently not possible. –  mark Jun 13 '10 at 22:58
