.XMMAP File Extension
File TypeMindManager XML Map File
What is an XMMAP file?
XML version of a diagram created by Mindjet MindManager, a visual diagramming application; stores a "mind map" made up of drawn objects, text, and other symbols; stores ideas captured during the brainstorming process.
The non-XML version of MindManager maps are stored in .MMAP files. The advantage of this binary format is that it requires less storage space. However, the XML representation is more transportable since it is more easily read by other applications.
