The latest uTorrent versions cause many problems when it comes to removing files/data with webui or via VNC in normal uT. Therefore, files/data must be removed via FTP. To prevent uTorrent freezing, please follow the steps for file proper removal:
1/ stop torrent in uTorrent (Webui or via VNC)
2/ remove torrent name from uT list , don't use option "remove with + data or torrent". Just use "Remove".
3/Now you can remove files via FTP.
We don't remove files via FTP first and later from uTorrent list!
