KTorrent ate my disk space!

So, I was trying to download an iso image of Arch, just to try it out in a VM. But my cpu overheated and shut off, right in the middle of the download. I let it cool, then booted back into OpenSUSE, opened KTorrent, and the download was gone. Reopened the torrent, it restarted from the beginning. Is there any way to reclaim the disk space? I dual boot Win7 and OpenSUSE, and I only gave linux 20GB of hard drive space, so it’s kinda important.

just use a file manager to delete the file from ktorrent’s tmp folder.
I forget the location but you can see it from ktorrent’s settings.

Thanks! I’ll be hunting for that folder now…
