I have been using Bitcomet for over 10 years and haven’t had any problems till now. When I download a movie file/clip, it saves it as “Unknown File Type”. This only happens with these type of files. Pictures, games and programs down just fine. I’ve switched to UTorrent till this is resolved…Thank you…
Are you using magnet links or did you download and start the torrent file itself?
Which type of files? Can you provide us a download link for test?
