How do you iterate through every file/directory recursively in standard C++

Hello everyone!

I've been looking for a way to check if a determined folder is empty or not, and if it isn't, list the existing files in the folder, but of course to no avail.

I've been looking around and found something called dirent.h and something else called boost. Is there any way to achieve my goal without using this? If there isn't which one would be the best bet?

thanx in advance
