Recursive search of windows directories

It has been awhile since I've used C++ and need some help. I'm just trying to create a simple binary to recursively search the windows directories. I just can't find any information on how to load the appropriate headers, etc.. to actually use extensions or anything useful on manipulating directories in windows. I used java for a bit and it was incredibly simple, so I'm a little frustrated with this. Anything you can offer will be appreciated.

If you are OK with boost, this might help.

Boost is my new friend. Thank you sir.
