The vdb3 file extension identifies a database used by the VistaDB embedded relational database engine from VistaDB Software. VistaDB is designed for applications that need a database integrated into the application rather than run as a separate database server.
A vdb3 file stores structured relational database data used by the application, including the application's records and supporting database information. The file is part of the data used by software that has licensed and integrated VistaDB.
VistaDB databases are associated with Microsoft Windows software, including Family Tree Maker. The file should normally be managed by the application that created it rather than edited directly.
On Microsoft Windows, open a vdb3 file with the Family Tree Maker installation that created or uses it, or with compatible software based on the VistaDB database engine.
If the file belongs to another application, use that application to access its data. VistaDB database files are not intended to be opened as ordinary documents.
Open a vdb3 file in the associated Windows application or compatible software based on the VistaDB database engine. Use the application's or tool's database export features, if available, to save the data in another format.
Do not rename the file extension as a substitute for conversion, because that does not change the database format.
