Security Explorer - Version 1.0 Security Explorer operates just like Windows Explorer. All the things you are used~to doing in Windows Explorer will work in Security Explorer. The main visible ~difference is the new pane in the bottom section of the right side of the window. ~This pane shows the current Access Control Lists (ACL's) for the currently selected~file or directory. Each ACL consists of a user or group that ACL applies to, permission~settings and flags. All these are shown in that pane.
