torrent assembly help..

so i downloaded a torrent today, and for some reason its broken up into multiple pieces. can someone tell me how to make it one piece so i don't mess something up.

if its multiple .rar's, then if you unpack part 1, it will automatically piece together.

so do i unpack them all at once?

it worked thanks

No, just unpack one, they usually say "part 1" "part 2", and i usually just unpack the "part 1" and then when its done they automatically piece together even without clicking on the other parts at all. I know its weird, but if you're talking about what i think you are, trust me it works.
