First you have to download and instal the Bit Torrent program, mine was already on computer so I don't know the url to get it. And then you can search for some torrents.

I'd recommend these sites.

Remember that theres some torrents that contain V_i_r_u_s_e_s, so if you get any that are a weird file type, require a weird compression tool, or player it just better to delete them. Then Try Try again.
