Visual Studio - 使用“从现有源向导创建项目”时的新过滤器而不是新文件夹

I used the Create Project From Existing Code Wizard for Visual Studio 2008, but apparently projects created this way do not allow you to create virtual solution folders, and instead only allow you to create actual system folders. I would like to have the standard project setup of Header Files, Resource Files, and Sources Files, but I seem to be unable to create the virtual files required. Is there any way to change the project so that it allows virtual folders to be created?I used the Create Project From Existing Code Wi
