^ Have you installed dropbox on both machines?
I'm not 100% clear what you mean by 'target folder' -- as I said above Dropbox will sync the contents of the chosen 'dropbox' folder from one machine to another.
You'll have to install it, and log in on both machines
I have Dropbox installed on both PC and Laptop and I'm signed in on both.
As the PC is new I want to transfer a lot of files from my Laptop across and then keep them synced - so I select some files from their parent folder on my Laptop and then drop them into the Dropbox folder (which I've previously named). Now I know I can access these files from my PC (I saw them appear in the Dropbox folder on my PC) but I'd like them to be synced with a folder on the PC (target folder) but I'm not sure how to do that.
Or am I missing the point? Are you supposed to use the files in the Dropbox folder? Ideally I'd like to add or amend files in their parent folder (either on PC or Laptop) and they update in their parent folder on the other device???
Sorry for this confusion!!
