However, you need a torrent client to do it.
Among the free ones, there is BitComet.
Features and Highlights
The disk cache mechanism in BitComet is an interesting feature.
Moreover, BitComet can preview files while they are being downloaded.
If you want to preview more, ui.preview_any_file must be enabled.
It is a part of the advanced functions of BitComet.
However, this may not work well when there are only a few seeds available.
BitComet prevents your system to sleep by default.
