I'm a bit confused. A few years ago I read about torrent v2 which had support for per-file hashes so that you could participate in multiple swarms where the file is exactly the same (e.g., a 15GB movie), but where different torrents are SLIGHTLY different because someone added a 50 byte text file stating 'uploaded to some.annoying.website.com).
When I downloaded an example v2 torrent file, it didn't work (there was an error about it being the wrong length).
How do I get v2 torrents to work? (I'm on the latest v4.6.5 for Windows 10 Pro x64 English)
