The rmgc file extension identifies the main database file used by RootsMagic, Inc.'s genealogy software. It stores a family tree and its associated genealogical information, including people, relationships, events, sources, and notes.
The format was used by RootsMagic 4 and replaced the earlier .rmg files. It is a legacy RootsMagic database format rather than the default format of newer RootsMagic releases.
RootsMagic is available for Microsoft Windows. A compatible version of RootsMagic can use an rmgc file as the working database and can upgrade or import it for use with a newer database format.
Open an .rmgc file with a compatible version of RootsMagic for Microsoft Windows. If a current release does not open it directly, use its database import or upgrade option to transfer the file.
RootsMagic can export the genealogy data from an .rmgc file to GEDCOM for use in other genealogy programs. To continue using the data in a newer version of RootsMagic, use that version's import or upgrade workflow rather than a general file converter.
