Losing Torrent after Download complete

How to explain…

Up loading and downloading torrent files isn’t my problem, my problem is after successfully down loading a torrent to my “C” drive i then transfer the file to my “E” drive. After a while the torrent file disappears from the folder in my “E” drive.

What am I doing wrong.

… After a while the torrent file disappears from the folder in my “E” drive.

Are we talking here about the real .torrent file that Bitcomet opens prior to starting any download or are we talking about the file(s) that is/are referenced in the .torrent file, the “contents” of the torrent, so to speak?
