First of all, we can't see your screenshots. You need to upload them to an image hosting sitemyphotos.mypclinuxos.comtinypic.com
Then share your image's link with us so we can all see it
Second, if I understand correctly, you want to be able to sort your torrent downloads according to content. Movies should go to a movies folder, music to Music and so on, right? I'm not aware of such a function in Ktorrent. Only thing I know is that the application can move completed downloads to a different folder, like you said.
When you add a new torrent for download, a window pops up with info on that torrent. From that window, you can change the save location and select another folder. You can also choose to save in your default folder and then move it to the folder you specify.
So, if you're downloading music, you could save it to the Music folder right from the beginning.
