How do I locate:
1.  A directory by name somewhere off the root, i.e. "C:\\*\*anywhere*\\DirectoryNameWIthUnknownLocation
2.  A specific filename in an unknown subdirectory, i.e. "FileWIthUnknownLocation.BIN"
with both searches starting at the root directory of a hard drive (not Internet)

You're going to have to use a recursive directory search that looks something like this:

char* MyFindFile(char* root, char* name, BOOL isDir)
{
  if (isDir)
  {
    dir = forEachDirInRoot(root)
    {
      if (Matches(dir, name))
        return root + dir;
      else
        return MyFindFile(root + dir, name, isDir);
    }
  }
  else
  {
    file = forEachFileInRoot(root);
    {
      if (Matches(file, name))
        return root + file;
    }
    // not in this dir
    //
    dir = forEachDirInRoot(root)
    {
      return MyFindFile(root + dir, name, isDir);
    }
  }
  return NULL;
}

Note that this is pseudocode, but it would be coded like that.
