Sorry about the simple question.
I searched the forum for open file but no luck.
I go to Code::Blocks\File\Open... then try to select my project or 'main' file with the code but the 'main' file does not appear under my project folder which opens up to Debug but has nothing.
Please help as I'm just making a new Project each time and copying the code from my previously made 'Main' folder after opening it in Notepad++.
Otherwise, thanks Code::Blocks. Some much more user friendly than CodeLite which I've been getting forum support for 1 week and the install is still not working.
