Advanced Settings
Shared Folders (Access restrictions)
To use Access Restrictions for a share, select
Enable.
Highlight groups or users in the All Groups/ Users column and use the left-pointing arrow buttons (located just to the left of each box) to move individual groups or users from the All Groups/Users column to the Read Only box (if you want to give them read access only) or all the way to the Writable box, if you want to give them full access to the share. Right-pointing arrows will move highlighted users or groups back to the right.
Click Apply when you have your groups and users in the appropriate boxes.
To set up new groups and users, see pages 41 and 42.
