Firstly, thanks for the detailed explanation of server/client syncing. Thought it had answered all my questions.
I successfully imported 2 DBs from iMac to laptop. I thought I had successfully imported my most important DB but, alas, no. The DB is fairly large and has over 30,000 items (my filing system). Its structure is a primary file with always a sub file. The sub file structure may have sub sub files or sub sub sub files (nested) in the sub file.
DPO has imported most of the Inbox (but not all) but the sub file structure is all over the place. Many of the sub files are missing yet some of their sub sub files and sss files and contents are there.
Any suggestions as to how I can get the imported DB properly in sync with the server DB?
