When you choose where to save the torrent that will be downloading you can choose if you like to just download some of the containing files.

I find this handy because sometimes you can check out the quality and so forth, really handy for DVD rips as you can download the small DVD title track before the rest.

The thing is, how do you then go on the get the rest of the torrent? -without redownloading what you just got if possible.

Err, you go to Files tab in Info Widget (you might have to enable a plugin) and check files you want to download.

Ah thanks, it's via a plugin.

Thanks!
