change the projct location

I have a visua开发者_如何学编程l studio 2008 project in the directory like

C:\Users\espl\Desktop\hello\world\helloworld(.sln file)

Now I want the solution file in the directory like

C:\Users\espl\Desktop\hello\helloworld(.sln file)

just outside the world folder.I just copy the project folder and paste it in required folder.but the modules are not loaded.So how it is possible.

---

Three options:

• Edit the file by hand. They're just text files
• Create a new blank solution and use "add existing project"
• Open the broken solution, remove all the broken projects, and add existing projects as per second option

I think I'd suggest the second option.
