If you need to browse files in TNAS or write data to the device, select your TNAS in the menu and click 

“File 

Browser”

 (Note: At this point, you need to have a username and password).

Map Drive:

By mapping your drive, you can simplify file management by creating a shortcut to frequently used folders. 
To create a mapped drive, select your TNAS and click 

“Map Drive”

 (Note: The Mac OS version of TNAS PC 

does not have this feature).

Change IP:

You can use the 

“Change IP”

 option to manually change your TNAS IP address. You may need to do this if 

your TNAS IP address conflicts with the network IP address segment. Otherwise, TNAS will be inaccessible.

installed  onto  your  TNAS.  Please  see  the  section  on 

“Initialisation”
