title: Delete files using pentaho
body: <p>I want to know how to delete files based the creation date using a kettle job. I have a log folder which contains log files for last one year. But I want to keep only last week log files. The job should be deleting all the log files which are more than one week old.
  There is a delete file option in pentaho job. But how do we get file creation date and delete the files accordingly</p>
