Files with the .mmmp extension are mind map parts created by MindManager Pro software. These files store a component of a mind map diagram to be used in other maps. MindManager is used on Windows and Mac to visually organize ideas, plans, and projects.
To open an .mmmp file, use MindManager software. The files can probably be converted to other formats as well. If you have problems opening an .mmmp file, you may need to update MindManager. The file download could also have been interrupted, resulting in an incomplete file that cannot open. In that case, redownload the .mmmp file.
