title: How to send source code - very common question
body: <p>I wanted to know what part of the project I need to copy for my USB for example in order to get the source code of the project. Do I need to copy the whole folder? Or do I need only the .sln file? Or..?because I've tried to copy the .sln file and when I try to open it with the other computer, it says that it can't open it for some reason.
  Thanks in advance.</p>
