Choose Properties from the File Manager Selected menu or from the icon's pop-up menu (displayed by pressing Shift+F10 or mouse button 3).

Click Add in the Add Access List Entry dialog box.
The other three required ACL Default entries are automatically created for you, with permissions set to no-read, no-write, no-execute.
(Optional) Change the permissions for the required ACL Default entries that were automatically created in Step 6 above.
Use the Apply Changes To option button to choose the scope of the changes.
The options are This folder only (default) and This folder and its Subfolders.
