How we Edmx when we add it into a folder.

I am working with edmx  everything is work fine. problem is occur when I add the edmx into a folder then it give me error.

All definition into app code data when I use into without adding a folder its work fine but when I put  edmx definition into  a folder then It can’t work  I think   there are problem in connection string following my  connection string definition .

<connectionStrings>
    <add name="TestEntities" connectionString="metadata=res://*/App_Code. TestModel.csdl|res://*/App_Code. TestModel.ssdl|res://*/App_Code.TestModel.msl;provider=System.Data.SqlClient;provider Security Info=True;User providerName="System.Data.EntityClient" />
  </connectionStrings>

 I think this definition will be change when I add them into a folder my folder name is MyEdMx.

My be I am correct or non please help me how I solve it when I place my edmx into a folder it give me an error
