What is a .MMAP file?
Ideas as a tree - saved in a handful of formats.
An .mmap file is a mind map created by MindManager, a diagramming app now owned by Corel. Open it with MindManager (paid, trial available) or import it into XMind for free. If you just need to read the content, ask whoever sent it to export a PDF, or rename the file to .zip to pull out any attached files.

Frequently asked questions
Is my .MMAP file uploaded?
No. Your .MMAP file is read and drawn for you.
Can I edit the map?
This is a viewer: you can fold and unfold branches, search and export, but not change topics. Export to OPML and import it into your favourite mind-mapping app to keep working.
Why does my XMind file show a warning topic?
New XMind versions also write an old-style content.xml that only says “created with a newer XMind”. The viewer reads the modern content.json first, so you should see the real map - if not, the file may be damaged.
Does it show notes and links?
Yes. Topics with a note get a small note icon; hover or open the outline to read it. Links are clickable in the outline.
