title: Can't run downloaded files in IntelliJ
body: <p>So I have this problem with IntelliJ every time I run a Java file from a .zip file. Every time I open a .zip file and try to run the Java file in IntelliJ, I can't actually run the code within the file. It opens, and there is no error in the code itself, but I'm literally unable to click the button that let's me compile and run the code.</p>
  
  <p>This isn't an issue when I create the Java file from scratch. However, if I download a .zip file, or if I zip the folder with my Java file in it, I am presented with this same issue. Can anyone help me? This has made working with this IDE a living hell, and I'm not allowed to switch out from it.</p>
  
  <p>I understand this probably is a poor explanation. If there's anything else I can provide, please let me know and I will be more than happy to oblige. </p>
  
  <p>This is a "picture" of the problem. The file extension should be <code>class</code>, not <code>java</code>. And the play button on the right should be green.
