title: WebStorm is ignoring some files contained in project folder
body: <p>from time to time WebStorm ignores some files that are inside project folder when I am trying to search for them through <kbd>Ctrl + Shift + N</kbd> (search file function).</p>
  
  <p>Here is picture:

  <p>I am trying to search file <code>edit-driver-license.html</code>. As you can see, this file is really there so WebStorm should find it. </p>
  
  <p>When I go to native windows file explorer and move the file into another folder and then back, WebStorm refreshes project structure and find the file. So problem solved.</p>
  
  <p>But when I restart WebStorm, everything will be like before and the file will not be able to be found...</p>
  
  <p>Is there any solution for this? Like, is there some ignore file list, or is this just a bug? This is not the first time it happened. I had same issues earlier, but I fixed it by restarting WebStorm.</p>
