Ron,
Sorry for the confusion. I didn't give you the right menu path. Yes there is a "Tools -> Import and Export Settings..." option; that is for importing and exporting the file itself.
What I intended was "Tools ->
Options... -> Environment -> Import and Export Settings". This was poor naming on MS's part because there is not import or export in this area of the options dialog.
Now you can refer back to the rest of my last post.
Regarding solution file locations:
When you create a new project in visual studio, typically the solution file will get saved along side it. I know that I have see where it will save a solution file in your default solution/project path. However I think the only time I've see that is when I open an existing project that doesn't have a solution.
One answer is simply: don't open projects, open solutions. Every project I work on has some project dependencies so I have to work in a solution context in order to load all the necessary projects. In my case, I can't just open a project as it will never work.
There is a MS white paper on team development that discusses solution structure and team development. It's well worth a read for anyone doing VS .NET development.

Working in teams with many projects can be complex. I have organized 3 different teams at 3 places I've worked so far so I have some experience with it. If you would like, start a new thread with some details about your environment and I'll see what I can help with.
