Data file
What is a .rmgc file?
A .rmgc file is a RootsMagic Database (version 4-7). This is a data file — structured information used by a program rather than read directly.
How to open a .rmgc file
- Start with the program that produced it; that's almost always the right tool.
- Open it in a text editor to see whether it's readable text or binary.
- For database formats, DB Browser for SQLite or LibreOffice Base can often import it.
The registry records this extension against RootsMagic Database, so software from that family is the most likely match.
How to convert a .rmgc file
- If you can view the data, exporting to .csv is usually the most portable option.
