so i don't understand how it works and i have some questions

1) How can i remove shared files?? i have tried to share some active torrents but now i have the same torrents shared twice
2) Is it not possible to share something not active in the client?
3) All the users in the channels have Tixati?
4) i'm not connected to any channel but i find some results when i try i search..why?
