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.
Right click the solution folder to create a new project.
Change the default location path to add the new physical folder name right after it with the back slash. Something like...C:\Project\Test\New Physical Folder
Click the OK button to create the project
Then the new project will be put inside your new New Physical Folder.
