About SMMX
SimpleMind is a mind mapping app for the iPhone, iPad, Android, Mac and Windows, free to start with a Pro version. Its maps are .smmx files, which people send to others who don't have the app, and SimpleMind's own viewer runs only on Mac and Windows.
An .smmx is a ZIP holding document/mindmap.xml: each topic with its place, text, note, style, checkbox and the topic it hangs from, the relations drawn between topics, and beside it the pictures the topics show.
Filepeek shows the map as an outline, its topics nested as they hang from each other in their colors, each with its note, checkbox, picture and link, and the relations lead to their other end. Filter keeps the topics that match, and Export saves it as OPML, Markdown or FreeMind's MM.

Questions
How do I open an .smmx file without SimpleMind?
Drop it on this page or press Peek an SMMX. Every topic shows in an outline, with its notes, pictures and links.
Can I open a SimpleMind map on a phone without the app?
Yes. Filepeek runs in your phone's browser, so the map opens as an outline on an iPhone or an Android phone with nothing to install.
Does a map with several central topics open?
Yes. Each central topic shows with its own branches, under the map's name.
Can I turn a SimpleMind map into a list?
Yes. Choose Export, then Save the outline as Markdown or OPML, or Save as FreeMind (MM) for another mind map app.
