title: Jenkins somehow creates ws-cleanup_timestamp file
body: <p>I have a Jenkins job, that triggers a script. Everything is ok, but in the foulder, where a script is placed, it creates a file with name</p>
  
  <pre><code>JOBNAME_ws-cleanup_TIMESTAMP
  </code></pre>
  
  <p>JOBNAME AND TIMESTAMP are variables from a Jenkins job.</p>
  
  <p>Why does it happen. Why does Jenkins create a file?</p>
