please, I need native code for copying a given sytem of directories,subdirectories, subsubdirectories etc and their file content.

    #include <windows.h>
#include <iostream>
using namespace std;
int main()
{
    SHFILEOPSTRUCT sf;
    memset(&sf,0,sizeof(sf));
    sf.hwnd = 0;
    sf.wFunc = FO_COPY;
    sf.pFrom = "d:\\masm32\\*.*";
    sf.pTo = "d:\\masm33";
    sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI;
    int n = SHFileOperation(&sf);
    if( n == 0)
    {
      cout << "Success\n";
    }
    else
    {
      cout << "Failed\n";
    }
}
