What is a RMGB file?
An .RMGB file is a RootsMagic Backup File. Users create these files to save their genealogy family tree data securely. The RootsMagic software packages the user's main database, multimedia links, and settings into a single backup archive. Internally, the .RMGB file uses standard ZIP compression.
How to open RMGB files?
The standard way to open an .RMGB file is to use the RootsMagic desktop application to restore the backup. Because the file uses a standard ZIP structure, you can also rename the extension to .zip and extract the contents using archive utilities like 7-Zip or WinRAR.
viewer.online/rmgb analyzes .RMGB files to identify their exact format and creator software. The tool shows which programs can open the file and usually previews the internal database files directly in your browser.
Best practices and troubleshooting
Keep your .RMGB files in a safe location, such as a cloud drive or external hard drive. If you cannot open the backup in RootsMagic, the file might be incomplete or corrupted. Try extracting the file with a ZIP utility to check if the internal database file is intact. If you are unsure what version of the software created the backup, viewer.online/rmgb can identify the actual format of your file.
