title: Where can I find the file format definition for a ZXING "Send History" ~.csv file entry?
body: <p>I scanned several items using ZXING, after which I emailed the scan history as an attached ~.csv file. I can't find the definition of the fields in the scan history ~.csv file record, though four of them are easy enough to figure out.</p>
  
  <ol>
  <li><p>Scanned barcode;</p></li>
  <li><p>Second copy of scanned barcode;</p></li>
  <li><p>Barcode format;</p></li>
  <li><p>Unknown; (sometimes used as file name);</p></li>
  <li><p>Timestamp; and</p></li>
  <li><p>Unknown. (Record delimiter?).</p></li>
  </ol>
  
  <p>Were can I find what the 4th and 6th fields are, and how they are generated? </p>
