You can lock folders and files to prevent users from copying, moving, renaming, or deleting them. You can copy-protect files to prevent users from duplicating them.

Note: Another way to prevent users from moving, renaming, or deleting files and folders is to give users Read Only access to the item containing them.

To lock or copy-protect files and folders:

1	Open Mac OS Server Admin and log on to the server you want to administer.
2	Press the Privileges button and choose Set Privileges.
3	Locate the disk or folder that you want to lock or copy-protect, then double-click it.
4	Select the "Copy protect" or Lock checkbox.
	When a folder is locked, only the folder's owner can move, rename, and delete the folder.
	When a file is locked, no one can move, rename, or delete the file.
	When a file is copy-protected, users cannot duplicate it.
	WARNING: Copy-protection does not protect files from being copied by programs that bypass the Finder.
