How to find out if a folder exists and how to create a folder?

Question

I\'m trying to create a folder if it doesn\'t exist. I\'m using Windows and I am not interested on my code working in other platforms.

Never mind, I found the solution.

Answer 1

Use boost::filesystem::exists to check if file exists.

Answer 2

boost::filesystem::create_directories does just that: Give it a path, and it will create all missing directories in that path.

Answer 3

The POSIX-compatible call is mkdir. It silently fails when the directory already exists.

If you are using the Windows API, then CreateDirectory is more appropriate.
