How can i chage the route for transmission torrent?

The actual route for download files in transmission is: /mnt/HD/HD_a2/Public/Transmission
I would like to change this route to a external USB disk that is conected to WD. The route in windows 7 for this usb disk is \WDMYCLOUDEX2\Elements_10B8-1 but i don’t know how can i use this route in transmision to download files in this USB external disk
Thanks in advance

Hi, my recommendation would be to use an SSH software with an interface like WinSCP and check on path to the WD Elements and use that path.
