I have a Visual Studio 2008 solution, and I would like to include a real folder in the solution, but not at the project level, instead at the solution level.
From MSDN:
"If you are working with a solution that contains numerous projects, you can use Solution Folders to organize related projects into groups and then perform actions on those groups of projects."
You don't want what the composer meant in Solution Folder. It made them to organize large solutions into groups.
For your problem, I think this is the job for your Installation Project to collect these files: Installation instructions, Global help, etc...
