OSMC + Deluge; How to get torrents to external HD

Hello there,

I’m sorry for what is probably a generic question, but I used this guide:

Apart from the bits that talk about setting up the external HD to install Deluge, it works fine which is all good. However I am having trouble working out how to get torrents to download to my external hard drive which is attached to the pi via USB. I’m sure it’s simple but I don’t even know the path that my external HD is set to, and I heard that OSMC mounts it automatically in media or something like that?

Anyway I’m just not sure at all how I go about this, and I’d like to learn how!
