This is just a quick question from a newbie.

It's been a while since I have done any type of programming. So I decided to give it a try by using code blocks. I have noticed that when I create a program there is a file which is has an extension named ".cbp". The question is, when I import a program and I want Code::Blocks to read it, do I do that by opening the ".cbp" file, or should I stick with the "main.cpp" file. Like I said it's been a while.
