Propagate Folder Permissions
If you change the access permission for a folder containing subfolders, the Propagation of Permissions dialog displays so you can choose to propagate the permission change to the subfolders as well.
Access Control List
In the Propagation of Permissions dialog, select one of the following options:
Do not propagate to child folders - the security settings are used for the current folder only. Changes are not propagated to subfolders.
Propagate only changes (append permissions) - any users or groups that have been added to or removed from the Access Control List on the current folder are added to or removed from the subfolders.
Any changes to users or groups assigned to the current folder are propagated to any subfolders that also have those users and groups assigned. This is the default setting.
Propagate entirely (replace permissions) - the Access Control List and the permissions are used for the current folder and all subfolders contained in the current folder.
Click OK.
Override the Access Control List
Security overrides that are applied to a folder with subfolders will launch the Propagation of Permissions dialog.
In the Propagation of Permissions dialog, select one of the following options:
Do not propagate to child folders–The security settings are used for the current folder only. Changes are not propagated to subfolders.
Propagate only changes (append permissions)–Any users or groups that have been added to or removed from the Override Access Control List on the current folder are added to or removed from the subfolders.
Any changes to users or groups assigned to the current folder are propagated to any subfolders that also have those users and groups assigned. This is the default setting.
Propagate entirely (replace permissions)–The Override Access Control List and the permissions are used for the current folder and all subfolders contained in the current folder.
