Description

Hey,

it would be cool if you could somehow select specific files to download from a torrent.

Like e.g. this archive.org torrent includes several encoding versions in one torrent, but I would like to download just one of them: https://archive.org/download/Time-lapseAstronautPhotographyOfEarthfebruary32012/Time-lapseAstronautPhotographyOfEarthfebruary32012_archive.torrent

Not yeat sure show torrent files work, but maybe it would also be possible to create a module for creating new torrent with only the desired file(s) in it:

torrent-select abc.mpeg < input.torrent > output.torrent

Best, Finn

Contributor guide

Research direction
Investigate the BitTorrent file format and how to parse a .torrent file to list files. Look at existing Node.js libraries like 'parse torrent' or 'bencode' to understand the structure. Then, implement a CLI option to select specific files for download or create a new filtered torrent.
