I would like to merge two http://burnbit.com torrent files(with identical piece lengths) into multi-file torrent using Bencode Editor so there is no need to download all files to recreate torrent. I added file list easy and merged piece hashes(Item->Merge with). It validates ok but after opening in utorrent I get error "torrent contains no piece hashes". Verified using this formula and piece string appears is too long: pieces = ((filesize + piece_length - 1) / piece_length) * 20 Why?
