hi,
When I uncheck unwanted components of a download, their status changes to Not Downloaded in the Download Priority column as expected, however the unchecked items are still downloaded. Am I missing something here?

See attached image for further clarification.

Many thanks.

look up cross-file pieces. There are dozens of threads here and at the support forum on why this is a necessary part of the bittorrent protocol

@chrishirst when an issue is not caused by qBittorrent, ask the user to close the issue. If not, sledgehammer has to do it.

Bittorrent works in fixed-size chunks. By necessity, when a chunk goes from one file to another, finishing one file necessarily also causes you to download the start of the next file. And when a file is tiny, like that .nfo file, downloading the .mp4 before it basically means the .nfo file gets carried along for the ride.

This is not a bug but rather a side effect of how the Bittorrent protocol works.

I have a workaround for this. Commented in duplicate issue:
https://github.com/qbittorrent/qBittorrent/issues/4980#issuecomment-243959482

@WhosAsking this is a bug. Because qBittorrent don't prefer your selected files and download much more.
If use workaround from above link you will get the expected behaviour: qBittorrent download only selected files and only them.

From the FAQ:
As you may know, a torrent is split into pieces of equal size that do not take files into consideration. As a consequence, a piece can contain information relative to more than one file and qBittorrent only operates at piece level. Because of this, if two files are adjacent and you choose to download only one of them, it is likely that the filtered one will be partially downloaded and thus appear on the hard-disk.

Again, this is not a bug. It's expected behavior, and I see it in other Bittorrent clients including Shareaza, Transmission, and Tixati. Anyway, there was confusion in past versions surrounding unchecked-but-downloaded-anyway pieces that is being cleared up.

Or can you show how an unchecked non-adjacent file (meaning it should be in a completely separate chunk not meant to be downloaded) that gets downloaded anyway?

Duplicate of #2659

Version 4.0.x is released. It uses libtorrent 1.1.x which puts the unwanted part files in the hidden file
".<torrent_hash>.parts" which is put in the same folder as the root folder(if any) of the torrent.
For the moment it's not possible to put that file somewhere else.
