Using torrent, you can easily download all that cost-free if it's seeded. However, just because it's available doesn't mean it's legal; if it's copyrighted, you run the risk of piracy by downloading it using torrent. Many countries ban the use of torrents by blocking websites of torrent clients and piracy websites.

Torrenting is often associated with piracy because it’s frequently used to share files that are protected by copyright, including movies, games, music, and software. However, torrenting also has many legitimate uses, such as lessening the load on centralized servers by distributing the hosting burden among users.
