title: Sitefinity CSS versioning triggers
body: <p>I found the following link describing Sitefinity's built-in CSS file versioning feature, but it lacks detail and unfortunately I can't find anything in Sitefinity's documentation.

  <p>It seems that files in the following folder will automatically get a version number:<br>
  ~/App_Data/Sitefinity/WebsiteTemplates/[YourFolder]/App_Themes/[YourTheme]/Global</p>
  
  <p>But, if you have them in a subfolder such as:<br>
  ~/App_Data/Sitefinity/WebsiteTemplates/[YourFolder]/App_Themes/[YourTheme]/Frameworks/Telerik<br>
  Then versioning doesn't get applied. </p>
  
  <p>What I'm trying to understand is what the actual triggers are for incrementing the version number?<br>
  When we deploy code we'd like to know that the user is going to get a fresh copy of all CSS files. </p>
