I found some discrepancies in RootsMagic and posted a question. This was in an answer:
C:\Users\Tom\AppData\Roaming\RootsMagic\AMT (change the “Tom ” to your Windows username). In this folder is a .DAT file for each connected Ancestry Member Tree (AMT), named “AT-AncestryTreeID.DAT”, where AncestryTreeID is an integer. This file is a SQLite database containing tables named identically to a subset of the TreeShared RM database file.
Is there any data description documentation on that file? Or any documentation on its purpose in life and what it does.
