LazyWolf, thanks a lot. It's still true, the .sync folder does not exist on my systems, which is due to the used packages, I guess. On Ubuntu – Sync installed by PPA – you will find the sync.log in /home/username/.btsync On the Synology NAS – Sync installed from SynoCommunity – you will find the sync.log in /usr/local/btsync/var Someone my add this in the named page. Cheers, btmax
