VS 2010, change location of project file

Question

I do not with VS 2010 frequently so my question is "beginner".

VS2010 creates a solution with the folowing directory structure (simplified):

/Solution
    solution.sdf
    solution.sln
    solution.suo
    /Solution
       solution.cpp
       solution.vcxproj
       /Debug
       /Release

I want to change the directory structure for alredy created project:

/Solution
    /Solution
       solution.cpp
       /Projects
           /VS
              solution.sdf
              solution.sln
              solution.suo
              solution.vcxproj
              /Debug
              /Release

So the solution file and projects file will be moved into subfolder

 /Projects/VS

The file solution.sln was enough to edit the path to

 = "Solution", "..\..\solution.vcxproj"

But how (and where) to change a location of the project file solution.vcxproj so as to be able to locate all files with the source code.

I am using different compilers so I want to create own subfolder for each development tool.

/Projects
    /VS
    /Eclipse
    ...

Answer 1

= "Solution", "..\..\solution.vcxproj"

No that's wrong, the .sln file is in the same folder as the .vcxproj file. So it should read = "Solution", "solution.vcxproj".

The only other patch is that the solution.cpp file is in a non-standard location. Edit the .vcxproj file and locate the <ItemGroup> for the solution.cpp file. Change it to Include="..\solution.cpp".
