Super Q-pointers are extended Q-pointers used to access non-D3 and/or nonlocal files.
A Super Q-pointer is a Q-pointer to a file that is not in the local D3 file system. The first attribute is a Q, the second attribute is blank, and the third attribute contains a host name (from the hosts file), followed by a colon, followed by the file name on the remote file system.
The first attribute can also be QS in which case the file-save process saves the entire remote file as if it existed on the local machine provided the save is used with the e option. This data can then be restored into that same remote file or into some other file.
