title: Removing all ACL on folder with powershell
body: <p>I'm pretty new to powershell scripting (nearly 1 month since I started learning powershell.)</p>
  
  <p>I'm currently working on a script with powershell 2.0 to clean folder NTFS ACL. I want to delete every acl except the administrator one.</p>
  
  <p>My problem is that I can't find a way to delete every acl that are not administrator, without knowing them.</p>
  
  <p>So I came here to sought for powershell pro.</p>
