Please, can you tell me if that library can download the parts in the order?

yeah good idea !

Downloading parts in order goes against the point of the BitTorrent protocol. If everyone tries to download the first parts first, no one will get them.

The algorithm implemented in ttorrent follows some of the recommendations of the BitTorrent protocol spec and favors the least available pieces first to increase the overall availability of data amongst all seeders.

If you want though, it is fairly easy to change that algorithm and use a different algorithm. The piece selection happens there: https://github.com/mpetazzoni/ttorrent/blob/d243274ad77c098b2c5f2028b25f706313e3e479/src/main/java/com/turn/ttorrent/client/SharedTorrent.java#L648
