## ACL permissions

ACL permissions are fully supported when using properties, preserve attributes and the synchronizer. To view/modify the ACL permissions, select a file and use the &context-menu-lnk;: Properties Permissions Advanced permissions . At Copy/Move if preserve attributes are selected, the ACL permissions are also copied. The synchronizer keeps the ACL permissions as well.
