There isn’t a sync with the Finder. (Not intending to be pedantic, but proper terms help keep the discussion focused on the right topic.) Sync is a very specific operation in DEVONthink.
DEVONthink doesn’t monitor any external locations. However, you can use our Folder Actions with Pro and Pro Office to effect some semi-automatic importing. The Folder Actions are typically installed when you first launch DEVONthink, but you can install them from DEVONthink Pro (Office) > Install Add-Ons. After they’re installed…
- Right-click an empty folder in the Finder. This will be the folder that receives files to be imported into DEVONthnk.
- Choose Services > Folder Actions Setup .
(Note: macOS 10.14 Mojave will ask whether to allow this action or not. Allow it. Also note, it will ask every time you call open Folder Actions Setup, and this is under Apple’s control, not ours.) - Select the desired script from the list of scripts that appears and okay it…
- Quit Folder Actions Setup.
- Drop a file into the folder and the Folder Action should trigger soon after.
