title: User related files in IntelliJ IDEA project
body: <p>We have a small team using IntelliJ IDEA as Java IDE and manage our source code with git. The IDEA project was created as directory based format. I found some files under <code>.idea</code> are user related.</p>
  
  <p>Is there a complete list of user-related files that I can filter out with <code>.gitignore</code>?</p>
