Right now I'm trying to migrate from vuze to ktorrent, because vuze eats too much memory at its startup time now is not good.
Question: how to move all torrents from vuze to ktorrent?

Shift-I for importing is a bad variant because of much more than 100 of torrents.
Is there some easier way?

I also tried to play with scripts, but was unable to find function for importing torrent to specific directory(and using one directory is not ok - files were saved to different directories, though most of them are locating in /home/user/downloads/<something>/<something>/<torrent-content> where <something> varies for each torrent).

There is nothing really suited as a mass import tool at the moment.
