What is a .MSCZ file?
Ideas as a tree - saved in a handful of formats.
An MSCZ file is a sheet-music (music notation) document created by MuseScore, the free scorewriter. It stores notes, staves, lyrics, and layout, not recorded audio. Open it with the free MuseScore desktop app, or export to PDF to print it or MusicXML to move it into Sibelius or Finale.

Frequently asked questions
Is my .MSCZ file uploaded?
No. Your .MSCZ 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.
What about MindManager .mmap files?
Topic text and structure are shown (beta). Images, attachments, styles and relationships aren't displayed yet.
