Is there a way to add existing Folders to a Visual Studio Project so that I do not have to do this file by file?
Edit
To make it clear: I want to add references not copies.
If the folder and its contents have already been created and it physically exists under the Project, you can click the Show All Files icon (at the top of the Solution Explorer windows) and then when the folder shows as a dotted icon, right-click it and choose Include In Project and the folder and all its contents are added.
