title: Visual Studio as Code Browser : How to preserve the directory structure?
body: <p>I've downloaded source of an opensource C++ project. It is a Linux project. As Visual Studio is my favorite IDE  I want to use it to browse &amp; study the code. I created an empty C++ project and now want to add the source code to Solution explorer.</p>
  
  <p>How can I add the directory structure to "Solution Explorer". Dropping the root folder of source code on the project in solution explorer is not working. Its just adding the files to the project but directory structure is lost.</p>
  
  <p>Is there any way to preserve the directory structure? I do not want to recreate the directory structure manually.</p>
