title: Delete oldest Files in directory
body: <p>I have a question about deleting oldest file in a directory. </p>
  
  <p>Situation is as follows:</p>
  
  <p>I would like to limit the amount of files in a directory to 5 files. Once that limit is reached I would like it to find the oldest file in the directory and delete it, so that the new file can be copied in. </p>
  
  <p>I have been told to use filewatcher, however I have never used that function before. </p>
