title: How to use notepad++ as external editor for 7zip
body: <p>When using 7zip, clicking "edit" on a file inside of an archive, per default opens up notepad. How to use notepad++ instead?</p>
  
  <p>7zip has the option to configure an external exitor.
  Simply using the notepad++ exe does not work. Edit fails in notepad++ with an error message similar to "file cannot be saved, because it's already opened in another program" (I don't have an english installation).</p>
