I got used to switch my distro(s) from time to time (of course not my Torrent client...), but what is becoming more and more annoying is to import all of the torrent files for further down- and uploading. And after a cute (kind of foolishly self-made) system crash some days ago, I now would have to import all my ~94 active torrents again, starting with a mere share ratio of 0 (instead of 4,66 or so).
Next step thus was to copy all the $HOME/.kde/share/apps/ktorrent/tor* into the new distro's dir (what seemed to be kind of simple as I had it already sourced out on another partition). But when starting KT again, it wanted me download anything newly, plus loads of error popups, so destabilised that it was likely to crash at the very try to manipulate the torrent list, and eventually didn't even start up again properly. Yet some files for download got unchecked, strange enough.
While browsing through the tor* directories (of curiosity) I found there per dir some obligatory sounding files (torrent, tracker ...), a cache subdirectory, one called \"dnd" (I wondered if those have to do with the download status of the single blocks, until I discovered them funnily empty), and a directory called the same as its super-directoy, filled the same, but instead a new, identically named subdir was dnd filled with binary files named as the torrent contents \- and (as I leech mainly Francophonically named music) mostly double ('...é..." and "......" and so on), obviously of file name encoding trouble. By a closer look, at nearly every, even fully downloaded torrent, the last few percent got lost, and sometimes single files which oddly had been downloaded nearly completely before, as they were unchecked then.
In a total, this looks quite a bit too strange to trust further for long-term loads (no idea what's coming next...). But I also don't want to re-import my whole torrent mountain again. So what about a tool able to extract necessary information about the active torrents' list and to write in a preferably platform-independent, and preferably safe way (perhaps kind of XML or so). I don't know anything comparable from other software (soonest maybe KGet's transfer list export functionality), so that distro junkies should know who's their best friend to torrent...

You can just store the tor directories on the same partition as the data, (folder to store temporary files in the settings)

Next time you reinstall, open KT, change the temp folder and restart KT, then it should find all torrents and no importing is needed.
