Support seeding even for torrents with "Missing Files"

[SerVB]

Sometimes I download a torrent to 100%, and then over time delete some files from its folder manually. Seeding stops at this point.

At the same time, if I don't download a torrent fully by selecting the downloadable content files, it can be seeded even with not all files presented.

So I don't see what blocks torrents with "Missing Files" be seeded. Probably it's just not implemented, though...

Any ideas if it's possible?

Force recheck the torrent and let it re-download any cross-file-pieces it needs (into <hash>.parts file which is very small usually).

Thank you for the comment. However I've checked and it doesn't work for me well, unfortunately.

1. "let it re-download any cross-file-pieces it needs" – can such cross-file-pieces be considered as not-to-be-seeded, so no downloading of them is needed?
2. "Force recheck" stucks at "0.0% Checking" for me...
3. After I reopened qBittorrent, one of the force rechecked torrents just started to download all the files, even those that I deleted manually.

I may be wrong:

1. cross-file-pieces have to be downloaded and will be seeded as part of the torrent
2. isn't it in the queue of torrents to be checked? :-/ try restarting qbt
3. i have complained about the issue Erroneous torrent (missing files) should pause to prevent re-downloading if Recheck finds no files? #17626 where qbt starts downloading without asking me. If you have deleted file outside of qbt (via your OS file manager), and have files ticked in qbt, then it will download them again.

1. Probably you mean that this is the current implementation and limitation, because I still don't understand why this downloading is needed and why only pieces presented locally can't be seeded.
2. Probably no: I had two torrents "force rechecked" and both were "0.0% Checking" for some time. Other torrents were completed/seeding or downloading. After restarting qbt, as I mentioned, one torrent just started downloading all the files including removed manually from the disk. Another one was still "0.0% Checking".
3. Thank you for the link, is see there "Recheck actually means reset all and start from the scratch", so probably "force recheck" won't help with my original need – to continue seeding what can be seeded even for torrents which "Missing Files"...
