Untracked files randomly being converted to .!qb extension

[majora2007]

qBittorrent & operating system versions

qBittorrent: 45.0.1 x64 Operating system: Windows 10 Pro x64

What is the problem?

After downloading, I will untrack some files as I put modifications on them. Usually on qbittorrent updates, these files go from completely untracked to having !qb extension. If you remove this extension, the archives are usually corrupted after the fact.

I would expect once a file is untracked, qBittorrent would not perform any updates on the file.

See here, this torrent has been Completed with untracked and even so, my files have been broken.

Steps to reproduce

I'm not sure how to reproduce reliably as I'm not sure what triggers it. I've been going through my collection and I found 120ish different accounts of this. Sometimes checking the file will download the file correctly, usually I have to remove the whole torrent, download a new file to a different directory then stop seeding indefinitely.

I would be really nice if this can be investigated. Not seeding really defeats a lot of the purpose.

Log(s) & preferences file(s)

I looked for the logs, but it's showing for qBittorrent v4.1.5 despite not having a custom log location.

I have noticed similar on MacOS version too, previously completed files in a folder of many files, when I then unselect and select other files, they would sometimes end up with the .!qb extension again. In my case all files were still good, no corruption.

If you make modifications to the files, you need to remove the torrent from qBittorrent.

I uncheck the individual file and make changes to that. But the others I don't. My assumption is if you uncheck after downloading the qbittorrent will ignore it and thus modifications won't effect anything.

Removing a whole torrent when one file receives modifications does not make much sense to me and if that is the case, what does unchecking the file do after download?

[glassez]

Unchecking is just a short way to mark file as "Don't download". qBittorrent don't ignore any existing files.

[majora2007]

@glassez is there any appetite for a change such as this, such that after download, if unchecked, then qbittorrent ignores the files? As I'm assuming some sort of check is happening between versions or whatnot which is then appending the !qb extension and whatnot.

It would be a shame for me to have to stop seeding torrents just because I need one file within to have some sort of modification within.

I would also be curious why if unchecked afterwards, that qbittorrent needs to do anything with the file if it's then in a "do not download" state.

"do not download" means just "do not download" literally. It doesn't affect any existing data, it just don't download new one. This is all that libtorrent provides us with. And it seems that our request to add the ability to really ignore some existing files remains unsatisfied (and it seems even without understanding its necessity).

[majora2007]

I read through the request, it's a shame that this functionality can't be expanded upon. I'll close out my ticket. I upvoted the issue on libtorrent. I hope we can make some progress there as it would make a big impact for the torrent community I feel.
