what does this mean???
 

The other day I was watching this user that tried to download a file off my computer (video) and he/she had 3 uploads of the same file on my computer.. Then as I watched the file said UPLOADING HASH TREE I immediatley killed the uplaod becuase it didnt seem like they were trying to upload a file but something else... Can anyone explain to me what uploading hash tree means??

See stief's post in the thread below. Hash tree is nothing to worry about;)
