If you are exporting a complete .milkymap file through apps or other platforms outside of Milkymap, please be aware that those platforms can change the extension. If that is the case, please tell the recipient that they can remove the extension, like .zip, and keep the .milkymap at the end. Then they can just import that file. We know e.g. that Whatsapp is adding .zip to the filename.
When exporting the complete Milkymap, this will include images and attachments. Be careful what you export and share. This is at your own risk.
You can export Milkymaps in different formats, like PNG, Excel, PDF and .milkymap.
