A small helper script that finds all files in a folder that are currently not tracked by qBittorrent. This is useful if you use e.g. the excellent academic torrents or just create torrent files from your own data as a simple integrity safety. Checking the dataset on disk against the torrent checksums quickly flags if any of the files have been changed, or whether you stored intermediate files into the supposed source-of-truth folder.

qbittorrent-untracked to the rescue!

qbittorrent-untracked connects directly to the qBittorrent web API using your admin credentials, pulls the full list of files tracked in all torrents, and compares it to the list of files actually found on disk. It then shows you all the files or folders that qBittorrent isn't aware of; these should then be moved or deleted.

qbuntracked \
--host dataset-server.local \         # where you'd open your qBittorrent web UI
--torrent-root-local /nfs/datasets \  # where you mount your torrents *locally*
-x torrent_files \                    # exclude folder relative to torrent root
-x /nfs/datasets/untracked \          # exclude folder with absolute path
/mnt/pool/datasets                    # mount point of torrent folder on the server
