OK, I figured out my way, it seems that I could solve most of the
problems. My big problem now is that the recursive_directory_iterator
goes through a file which has a really long name. I think it's more
than 256 characters. It says:

boost::filesystem::last_write_time: The system cannot find the path specified:

Is there a fix or something for boost to handle more than 256
characters in windows path? I am using MSVC2010 + latest Boostpro
installer.

p.s. so far here is my code. If you have any idea about what I am
doing wrong, please don't hesitate to comment:

#define BOOST_FILESYSTEM_VERSION 3

#include "boost/filesystem.hpp"
#include <iostream>
#include <ctime>

using namespace std;
namespace fs = boost::filesystem;

int main() {
        fs::recursive_directory_iterator it_end;
        fs::recursive_directory_iterator it_dir("e:\\");
        fs::path p;
        
        time_t oldest( time(NULL) );
        time_t newest(0);

        try {
                for ( ; it_dir != it_end; ++it_dir ) {
                        p = *it_dir;
                        try {
                                time_t t( last_write_time(p) );
                                if (t<oldest) oldest=t;
                                if (t>newest) newest=t;
                                //if (fs::is_directory(p)) cout << (p) << " " << t << endl;
                        }

                        catch (const fs::filesystem_error& ex) {
                                cout << "\n" << ex.what() << "\n";
                        }
                }
        }

        catch (const fs::filesystem_error& ex) {
                cout << "\n" << ex.what() << "\n";
        }

        cout << "\nOldest: " << ctime(&oldest);
        cout << "Newest: " << ctime(&newest) << endl;

        return 0;
}
