title: how can i recover windows chk-files extensions in linux bash
body: <p>After a scan disk i have a lot of CHK-files in folders like "found.000", ...</p>
  
  <p>I can find out the extensions with the file command:</p>
  
  <pre><code>for i in /media/Daten/found.*/*.chk ; do file $i; done
  </code></pre>
