You can view POSIX permission values through the WebDAV, CIFS, and NFS protocols.

With the WebDAV and NFS protocols, permissions are represented by three 3-character strings: one for the owner, one for the owning group, and one for all others. From left to right, the three character positions in each string represent read (r), write (w), and execute (x). Each position has either the character that represents the applicable permission or a hyphen (-), meaning that the permission is denied.

For example, the string below means that the object owner has all permissions for the object, the owning group has read and execute permissions, and all others have only read permission:


The initial hyphen (-) indicates that this is an object. For a directory, the hyphen is replaced by the letter d. For a symbolic link, it is replaced by the letter l (lower case L).

Windows displays permissions in the Security tab in the Properties window for an item. These permissions don’t map exactly to the POSIX permissions used in a namespace.
