single files out of a multi file torrent

Hi,

in fact, qBittorrent usually use compact allocation mode as a default (doesn't allocate 100% since the beginning of the download). However, if you unselect some files in a torrent then the torrent will switch in ful allocation mode because of a libtorrent limitation that will probably be fixed in the future. If it allocates 100% although you didn't filter any files in the torrent then this is a bug and this should be reported.

Concerning the progress in the download list, it refers to the progress of the selected files only. Not to the whole torrent. The size indeed still refers to the whole torrent size, I guess I could fix this.

Hi,

so far so good, i managed that it wont allocate 100% (i think) (by pressing load first files first, so I can download the single files i mentioned before),
I tested a different torrent file, searched via integrated search -> i couldn't decide which to download qB added the torrent straight away, so i clicked on properties and disabled all but the first four.
I switched to the corresponding folder and .. there (i had to refresh a few times and saw them grow :) ) but i definitely wrote a fifth file. which I did unselect.

I cant reproduce the effect of correct loading when enabling "load first files first",

conclusion: i will report this behaviour as a bug after I testet some more without integrated search, maybe I find some clues

You said:
"-> i couldn't decide which to download qB added the torrent straight away, so i clicked on properties and disabled all but the first four."

Just activate the torrent addition dialog in program preferences.

Libtorrent doesn't support partial torrent downloading in compact allocation mode yet. This is not a bug because the unselected files won't be really downloaded. However, they will appear on the hard-drive at their final size (filled with zeros). I asked libtorrent author about this but this is not a priority for him.

Well, I'v maintain qbittorent in ALTLinux and some times ago switch to it as primary torrent client for myself. Right before that i'v use ktorrent. And you know - there is no such problem in ktorrent with partial download. May be it will be a good reason for quthor of libtorrent ? ;)

This is already fixed in libtorrent and qBittorrent v1.0.0. Where did you find this sentence? it is outdated and it should be fixed.

I'v asking to download only 16th episode.

Yes I'm aware of this. But you have to admit that all the other episodes do
not appear (which is way better). Your result here is due to the pieces of
the torrent. All the torrents are splitted into pieces (their size is
variable) and libtorrent can filter pieces, not files. The problem is that a
piece may contain parts of two files (for exemple here, you have a piece
that contain the end of 15 and beginning of 16 : we cannot filter this piece
because otherwise, the beginning of 16 would be missing.

I told libtorrent author that it is unperfect but he just told me that
libtorrent just can't filter parts of a piece. I'll ask him again soon,
always good to keep some pressure on developpers :p

Yeah! Pressure! :) Tell him that in ktorrent this problem handle much better (i.e. there may be ignored files on disk, but they 0 length )

oh yeah... and beside ktorrent there is Azureus and mTorrent :) And I hope qbittorent someday will be in the top3 of all archs :)
