Vista - Display Folders and Files on seperated locations in one Folder.

I have a WHS (1 Tb) and a large network Icybox drive (1 Tb). General folders
like Documents, Music, Pictures, etc. are on both drives. Now I would like
to see the contents of f.i. the Documents folder from both drives in one and
the same folder. If I click on an item, it should be opened from the right
spot. How can I do this on my Vista-notebook? Or do have to buy special
software? And when yes, which software?

simplest way would be to make a folder and create shortcuts of the files you need in there, although that depends on the number of files concerned.

Of course vista does the same thing with it's "special" folders like the start menu using junctions but not sure if they are user creatable.

seem to remember something i read somewhere that said you could , bear with me will see if I can locate anything.

Possible solution Here
I would take time to research the option and backup anything you can before you start not sure if it does everything you want but should be possible as the facility exists in the OS already, good luck
