title: What is the accepted file extension to use for pipe delimited files?
body: <p>I am parsing a file of data whose fields are separated by pipes. The records are separated by newlines. This is similar to a CSV file or even a TSV file (<a href="http://www.cs.tut.fi/~jkorpela/TSV.html" rel="noreferrer">http://www.cs.tut.fi/~jkorpela/TSV.html</a>), but I wonder what the accepted file extension for pipe delimited data is?</p>
  
  <p>I do not see one specifically mentioned in <a href="http://en.wikipedia.org/wiki/Delimiter-separated_values" rel="noreferrer">http://en.wikipedia.org/wiki/Delimiter-separated_values</a> and I have not found mention of one in the 5 or so StackOverflow questions I referenced. </p>
  
  <p>The WP article suggests to me that, by way of "extension" from comma to CSV and tab to TSV, the extension should be PSV. Not everyone calls a pipe a pipe though. </p>
  
  <p>Maybe there is a popular software package that uses pipe delimited data and has an extension for it, thereby setting the de facto standard?</p>
