Hi, I am a new user and am trying to get my head around Sync. I am using Sync to transfer files from my seedbox to my local machine and then having sonarr handle the files from the Sync folder. The problem is that Sonarr is copying the file before it has finished downloading. I have read on forums that Sync used to/should add a .bts extension until the file is completely synced but I cannot find any settings for that? Many Thanks in advance!
