ok so to the addtion of container code above this work

  WIN32_FIND_DATA ffd;

  void ReadDIrectoryFileNamesToList(char* dir)
  {
   HANDLE h = FindFirstFile(dir, &ffd);
   if(!h) ERROR_EXIT("error reading directory");

   do  {
    if (!(ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
      FileNameList_AddOne(ffd.cFileName);
   }
   while (FindNextFile(h, &ffd));

  }



int main(void)
{
//  ReadDIrectoryFileNamesToList("C:\\*");
   ReadDIrectoryFileNamesToList("*");

   for(int i=0; i< FileNameList_Size; i++)
       printf("\n %d %s", i, FileNameList[i].name );

   return 'ok';
}

so i got all teh names in list ..eventually i could sort it hovever i 
got bad experiences with my sorting routine

back then i wanted to revrite quicksort to be as simpel as possible and 
cookd a form that had an error but lost the ability to say which of the 
form is correct so i had a sort of quicksort trauma now
