file extensions in Visual Studio?

[firix]

Hi,

When I create the project in Visual Studio.

*.opensdf
*.sdf
*.sln
*.suo

With the above extensions
creating files.

What files are files that have extensions?

I'm not sure I understand your question? Every file has an extension. The solution file ends in .sln. What are you asking?

[firix]

question is

- Header files should use a .h__ extension (.h / .hpp / .hxx).
- C++ Source files should use a .c__ extention (.cpp / .cxx / .cc).
- C Source files should use .c (.c only).


I saw the extension
I understand what type of file

*.opensdf
*.sdf
*.sln
*.suo

What is the type of files with these extensions and How they work?
