title: Meaning of "IconResource= ..\.. ,(number)"
body: <p>My first question in Stackoverflow, I'm thinking in making a litle program to edit some folder icons on Windows, I searched for the meaning of the number after the path of the icon but find no answer, the system icons have diferent values, i.e:</p>
  
  <p>Music Folder</p>
  
  <pre><code>IconResource=%SystemRoot%\system32\imageres.dll,-108
  </code></pre>
  
  <p>Pictures Folder</p>
  
  <pre><code>IconResource=%SystemRoot%\system32\imageres.dll,-113
  </code></pre>
  
  <p>When we manually change an icon from a folder,usually is used(to  keep it in a removable media):</p>
  
  <p><code>IconResource=..\Icons\icon.ico,0</code></p>
  
  <p>There is any influence in that last number? Or it doesn't matter for that purpose?</p>
