title: Making sure that a script does not modify files in specific folder
body: <p>I'm writing a python script which copies files from a server, performs a few operations on them, and delete the files locally after processing.
  The script is not supposed to modify the files on the server in any way.</p>
  
  <p>However, since bugs may occur, I would like to make sure that I'm not modifying\deleting the original server files.</p>
  
  <p>Is there a way to prevent a python script from having writing permissions to a specific folder? I work on Windows OS.</p>
