Yes, "watch for changes" is on for all my synced directories, and on by default. According to https://docs.syncthing.net/users/syncing.html https://docs.syncthing.net/users/syncing.html > There are two methods how Syncthing detects changes: By regular full scans and by notifications received from the filesystem (“watcher”). By default the watcher is enabled and full scans are done once per hour.
