title: How to use Pentaho Spoon to rename files that do not have an extension
body: <p>I am new to using Pentaho Spoon.  I have about 100 text files in a folder, none of which have file extensions.  I have found that if I create a job and move a file, one at a time, that I can simply rename that file, adding a .txt extension to the end.  What I'd like to do is create a job that goes through and renames each file and adds the .txt extension.  I've tried using the regex, but can't seem to get it to work because there's no file extension.
  Any help would be greatly appreciated.</p>
