Will not sync files larger than 2GB between computer and Synology DS218j in Sync for NAS (Network Attached Storage) Posted December 9, 2018 · Report reply I have been using Sync Pro between my computer and phone with no issues. I just got a DS218j to store everything and want to continue using Sync mainly for the Selective Sync option. I installed Sync using the Armada38x package following these instructions: https://help.resilio.com/hc/en-us/articles/206664850-Synology I am able to sync photos and other files just fine. But when a video is over 2Gb, syncing stops. The percentage left doesn't change and the upload and download speed go to 0. I know photo station uploader has a 2Gb limit but I thought Resilio Sync wouldn't. Is there a setting or something to configure I need to do? Is it setting on DSM, my router or Sync?
