Sync database by importing files

I read instructions on how to sync databases on 2 macs. (The normal sync mechanism does not work for me and fixing it seems to involve changing our router which is beyond my technical skill. So, I am trying this work around.)

:blush: I left for vacation and cannot find the description of how to do it. I tried and I am duplicating the whole file. I really want to somehow just locate the files that are not duplicates.

Also when I was experimenting without instructions, I trashed the duplicate smart file and can not retrieve it. :blush:
