Just to share some important info with you guys

Xunlei will silently upload the files you downloaded every time when it is launched without notifying you and thus significantly slowing down your internet speed even though the program itself shows no upload task

Renaming,changing the location of the file and deleting the the torrent will not stop xunlei from uploading the file you have downloaded as i believe the client itself has its own way to detect the files you downloaded via it

Proof:
Try open xunlei and leave it for a while without any task and observe your upload rate .After that close it and check your upload rate again

So use it at your own risk as you will never know what items it is trying to send to others
