Run Process>Batch>Macro, click "Input..." and select the directory containing the files, paste

  if (i==0)
     print("\\Clear");
  getRawStatistics(n,mean,min,max,sd,hist);
  print(getTitle+"\t "+hist[139]);

into the macro box, then press "Process". When finished, use the "Log" window's File>Save As command to save the table.
