Sorry, no. All the deleted files originated from the remote machine. It was a matter of moving them back to the original folder... although I had to filter out files older than 2 hours to not move back files I actually did not want. Its going to take some time to sync back 50GB of moved data. I don't blame you guys for this... it is beta software and this is an acceptable consequence.
