What is it?

A tool to merge partial downloads in qBittorrent

Files have to be identical. Overall content of torrent can be different, only identical files will be merged

Download or build

Building

Install Rust

Clone the repo, and build

git clone https://github.com/tatref/qbittorrent-merger
cd qbittorrent-merger/
cargo build --release

Download

See releases tab

Usage

Get torrent hashes from qBittorrent

You need hashes from at least two torrents: one will be used as source, the other as destination.

Piece hashes are checked before copying data to files, so mismatching source/destination won't have any bad outcome

API access

Enable the API, and enable auth bypass for localhost (password is not handled yet)

Run the tool

cargo run --release --bin merge 75439d5de343999ab377c617c2c647902956e282 2dd3f21f3d7709139b589bbf42abd8598deef8a2 ...
