Using Special Permissions
Don't be misled by the long list of so-called special permissions that you see when you click Advanced on the Security tab, select a user or group name, and then click Edit. Whenever you use NTFS permissions, whether it's through the Simple File Sharing model or the more fullfeatured Security dialog box, your actions result in changes to this list. Using the built-in permission options-Full Control, Modify, and so on-actually sets predetermined groups of permissions here.
When dealing with unusual access control situations, the best solution is usually to start by applying the predefined basic permission that comes closest to the desired result. Then add or remove special permissions as needed. Table below lists the full set of special permissions that are applied when you set each of the predefined permission options.
