    sprintf(search_path, "%s*.*", folder.c_str());
    WIN32_FIND_DATA fd; 
    HANDLE hFind = ::FindFirstFile(search_path, &fd); 
    if(hFind != INVALID_HANDLE_VALUE) { 
        do {

            // , delete '!' read other 2 default folder . and ..
            if(! (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) ) {

            }
        }while(::FindNextFile(hFind, &fd)); 
        ::FindClose(hFind);
