title: How to create a sub-package and add existing files intellij?
body: <p>I have my project structure something like this.</p>
  
  <pre><code>|--daos
  |  |
  |  |--MyDBReader.java
  </code></pre>
  
  <p>But I want to change it into this one.</p>
  
  <pre><code>daos
  |
  |--readers
  |  |
  |  |--MyDBReader.java
  </code></pre>
  
  <p>Can anyone tell me the preffered way to do that with <strong>intellij</strong> preserving all dependencies and usages?</p>
