Yeah the clients are pretty bad. They do have a synology sync tool which is good, otherwise I did it manually for our photos since Adobe lightroom can organize folders nicely
What do you mean? (removed link)
Amazon's desktop app supports batch uploads and downloads, but not sync to/from Amazon Cloud Drive.
However, there are 3rd-party options for this:
• Arq: https://www.arqbackup.com/
• odrive: https://www.odrive.com/amazon
• Synology Cloud Sync: http://www.macdrifter.com/2015/06/synology-cloud-sync-adds-a...
So no desktop sync, only manual uploads and downloads.
