Introduction

Windows ACL allows the QNAP NAS administrator to configure file and folder permissions for the local and domain users on the NAS from Windows Explorer.  The administrator can add, modify, and remove Windows ACL permissions of the NAS on Windows XP, Vista, Windows 7, Windows Server 2003, and Windows 2008.
