Can't open projects on code blocks

Question

Hi all!
I can't open projects I have built.
When I open the folder of one of my projects ghrough code::blocks, all I see is "bin" and "obj" folders and not the "main.cpp" file.
And when I right click on a "main" file and choose open with "code::blocks", it says : "The project file does not exist..."
What should I do?

Answer 1

But source file are physically existents on hard disk? If yes, they are valid paths?
