To me, the scripts are so difficult to interpret as if they were encrypted. I searched on the net and found this little software:

Link Shell Extension
http://schinagl.priv.at/nt/hardlinks...kshellext.html

It has a built-in menu in your Windows Explorer so it's pretty easy to understand and make use of. What you do is install if (of course!) then pick the source file (i.e. the file you want to "copy") and select the hardlink location (i.e. where you want to "paste" the file) and voila it's done!

Frankly though, I see 0% performance improvement in terms of memory and CPU usage, but a drastic reduction in harddisk light "blinking" is observed. It really feels like the file is only read once.
