Reorganise database DGTT to DT on mac, how?

[BLUEFROG]

You have fundamental misunderstandings of the situation leading you to overcomplicated ideas.

1. You’re not going to move the database from DEVONthink To Go into DEVONthink. Each device has its own copy of the database.
2. No, deleting a database on one device will not delete the database on another. See answer 1 again.
3. Sync is always optional. There is no need to sync any database from any device. So if you don’t sync DEVONthink on the Mac, it logically has no effect on what DEVONthink To Go is (or isn’t) syncing.
4. Your documents are not stored in iCloud. Sync data is not your documents, e.g., you can’t go into iCloud Drive and pull a PDF from the sync data. The documents are in your databases on your devices.
5. “if i don’t use DT anyway, how can I move all the document stored in DT back in my normal Apple file folder?” This is very unclear what you’re asking.

PS: This is all covered in many places, including the built-in Help and manual and Help > Tutorials > Understanding Sync.
