Would that be hard to add such a feature in Ktorrent?
Is in case when new torrent file is necessary, which contain only some files of source torrent.

Can you explain this a bit more ?

Well, there is a problem like this: how good ever ktorrent is, it must be run into X. For various reasons it can be better to have console torrent client, which rises a further complication: most console torrent clients can not select which parts of *.torrent file must be downloaded.

I have two possible solutions in mind:

1. edit *.torrent file, so it only contain necessary parts
2. make console daemon for Ktorrent, which is doing the real job and Ktorrent is only a frontend. At best, daemon could be run on another machine.

Is it a dead end to ask something of that here?

You can't do that, seeing that what is part of the torrent is included in the info hash, which is used to identify the torrent. Change the content, and you change the hash, and the tracker won't know what torrent you are on about.

2. make console daemon for Ktorrent, which is doing the real job and Ktorrent is only a frontend. At best, daemon could be run on another machine.

That was never the plan, and so ktorrent was never designed that way. Switching to this kind of architecture, would result in a major redesign, lots of work and not a lot of benefit for most people.

At the moment, I have no intention to go this route.
