VS C++ 2010 Express - Solution folders - underlying folder structure on disk

OK. I need someone to explain to me the conceptual usage of Solution folders/projects.

Attached is what I have. I created a project called test but there seems to be 2 layers of test folder nodes.

Let's say I want to move the 3 moveable folders (projects location, project templates and item templates) to my D drive - d \ libraries \ documents \ Visual Studio.

Is the left-hand Solution explorer pane supposed to hold ALL projects that exist within VS C++? OR does it make sense to have a single solution folder (project?) for each program/project?


The link below doesn't go through the nuance of how to get pointed to the right place to start but is attempting to mirror the disk folder tree with the solution explorer view.
