What is a .RMGB file?
An RMGB file is a special type of file that is used to keep a safe copy of another file created by a program called RootsMagic. RootsMagic is a computer program designed to help people record and organize information about their family history, like a digital family tree. The file that RootsMagic creates to store all this family history information ends with .RMGC. Sometimes, to make sure this important family history information doesn't get lost or damaged, RootsMagic allows you to create a backup file, and this backup file ends with .RMGB. Think of it like making a photocopy of an important document so you have an extra copy just in case. These RMGB files are especially useful for keeping a safe copy of your family history on things like USB drives, external hard drives, or other storage devices. If something bad happens to the original .RMGC file, like it gets deleted by mistake or corrupted (damaged in a way that it can't be opened), you can use the RMGB file to restore all the information back to how it was.
To open an RMGB file, you need to use the RootsMagic program or a free version of it called RootsMagic Essentials. Both of these programs understand how to read the RMGB file and can use it to bring back your lost or damaged family history project. So, if you have an RMGB file, you'll want to make sure you have RootsMagic or RootsMagic Essentials installed on your computer to open it and access the information stored inside.
