Hoe to designate Finder.app as a separate virtual desktop?

How to designate Finder.app as a separate virtual desktop? I’ve done it before but can’t remember how.

I found a method. I searched my hard drive for Finder and found it in HD > System > Library >Core Services and then added it to the Preferences.

That’s it!

I’ve also added a note here: http://totalspaces.binaryage.com/apps2
