title: Prevent users storing files on dekstop
body: <p>Is there any way to prevent users saving / storing files (except shortcuts) on their desktop?</p>
  
  <p>Messy users like download or copy huge contents and store it on their desktop, and this uses SSD place however there is a HDD for storage.</p>
  
  <p>I want to be sure they place their files to the correct place (anywhere but desktop)</p>
