Traversing a directory tree in C++

Please take a look at http://en.wikipedia.org/wiki/Dirent.h

The reference also has a link to dirent.h implementation for Windows or you can use cygwin

If you want to just do it for Windows you can build upon this example

There are no standard filesystem functions, so you won't get any answers that use "plain C++". For POSIX systems, opendir is used. For Windows, FindFirstFile. I'm not sure about other OSes.

There's a reason people recommend Boost Filesystem—it's portable and takes care of all these details for you.
