title: PhpStorm what does this file tree icon (sheet with X) mean?
body: <p>A file suddenly has this icon and I can't see how it got it. I have searched <a href="https://www.jetbrains.com/help/phpstorm/class-diagram-toolbar-context-menu-and-legend.html" rel="nofollow noreferrer">context menu and legends</a> and <a href="https://www.jetbrains.com/help/phpstorm/symbols-reference.html#d342455e7" rel="nofollow noreferrer">symbol reference</a> on the JetBrains repository but can't see the icon.</p>
  
  <p>Also looked at <a href="https://www.jetbrains.com/help/webstorm/file-types-recognized-by-webstorm.html" rel="nofollow noreferrer">file types icons</a>. and the symbol is similar to "text file" but has the additional "X" in the corner, which to me implies deletion but the file exists. </p>

  <p>Stupid question but... I can't see what it is. The file still exists and the file is auto generated. What does this icon mean? </p>
