can i sync existing folders? in Sync General Discussion Posted May 9, 2016 · Report reply Ok, thanks for that but I need some more help if you can. so on my NAS which is one of the 2 devices, I enabled the Pro trial to test. Under "My Devices" I have now set new folders from other devices to disconnected. What would be my next step? Add "/mnt/sync/_data" on my NAS? Then what? What do I do on my MAcbook (second device) do I add the code for the "/mnt/sync/_data" share or do I first somehow link these 2 devices (not sure I need that) Or do I create a share on the MAcbook for "/Users/ovi/Documents/_data/" ? Sorry, this tool is very confusing and it changed significantly since I first tried it while it was in alpha/beta.
