What is an MDG file?

MDG files mostly belong to Mindomo. An MDG file is a file that stores mind maps and diagrams using a JSON structure.
It is mainly used as a Mindomo diagram file where the file holds the data for nodes, links, and layout details.

It stores the diagram information in a clear JSON format.

You can open it with Mindomo software for editing and viewing.

Some MDG files may also refer to MicroStation drawing files related to CAD applications.

If you suspect your MDG file is for MicroStation drawings, check if the file opens with specialized CAD software. For more details and support on the Mindomo version, visit the Mindomo website.
FilExt.com note: Always back up your file before making any manual changes, especially if you edit its JSON text directly.

These *.mdg files store diagrams created within Mindomo, saving the layout, content, and formatting of the mind map. JSON is the internal file format used for these files. Alternatively, the *.mdg extension can also represent MicroStation drawing files, used by Bentley Systems' MicroStation CAD software for creating 2D and 3D designs. MobiDrive Guard also uses this extension. This file format is classified as Diagram or CAD file.
