title: batch file to open custom filetype
body: <p>I have a custom filetype (.photon) that is read by a python script which I generally run like this in a terminal:</p>
  
  <pre><code>py C:\Users\greym\Desktop\photon\photon.py C:\Users\greym\Desktop\photon\test.photon
  </code></pre>
  
  <p>the last argument is the file that is read by the python script how I make it so I can click on that file and it will run it through the python script</p>
