On NTFS volumes, you can set security permissions on files and folders. These permissions grant or deny access to the files and folders. You can view security permissions for files and folders by completing the following steps:

  1. In Windows Explorer, right-click the file or folder you want to work with.

  2. From the pop-up menu, select Properties, and then in the Properties dialog box click the Security tab.

  3. In the Name list box, select the user, contact, computer, or group whose permissions you want to view. If the permissions are dimmed, it means the permissions are inherited from a parent object.

如果权限是暗色的,说明权限是从父对象继承来的
