title: Drupal 7.17 - Do I have to remove these files after installation?
body: <p>A site I'm currently managing has Drupal 7.17 on it.  I'm noticing the following files in the root of the website:</p>
  
  <pre><code>install.php
  CHANGELOG.txt
  INSTALL.txt
  INSTALL.mysql.txt
  INSTALL.pgsql.txt
  LICENSE.txt
  MAINTAINERS.txt
  UPGRADE.txt
  </code></pre>
  
  <p>Researching this, tells me that as of Drupal 7.16, they fixed a security issue that would allow arbitrary code to run in install.php that would allow the re-installation of Drupal that someone could run.  But basically, I am wondering if any of these files (if left in the server root) could cause problems in Drupal 7.17?  Do I have to remove these files for security reasons?  Or is this no longer a security risk whatsoever in Drupal 7.17?</p>
  
  <p>I understand that we shouldn't remove the <code>upgrade.php</code> file, but just curious on the rest of these files.</p>
  
  <p>Thanks, and this is probably a dumb question, but just felt the need to ask anyways.  Usually I remove these files when I install software on websites, but not sure how Drupal uses and/or misuses these files.</p>
