The SetAccessRule method adds the specified access control list (ACL) rule or overwrites any identical ACL rules that match the FileSystemRights value of the rule parameter. For example, if the rule parameter specifies a Read value and the SetAccessRule method finds an identical ACL rule that specifies the Read value, the identical rule will be overwritten. If the SetAccessRule method finds an identical ACL rule that specifies the Write value, the identical rule will not be overwritten.

To persist new or changed ACL information to a file, use the SetAccessControl or SetAccessControl method. To persist new or changed ACL information to a directory, use the SetAccessControl or SetAccessControl method.

To retrieve ACL information from a file, use the GetAccessControl or GetAccessControl method. To retrieve ACL information from a directory, use the GetAccessControl or GetAccessControl method.
