Create new mind maps
SimpleMind will ask you where to store the mind map. You can choose every folder, so you could, for example, choose iCloud Drive.
Open existing mind maps
The files tabs shows the list of recently opened mind maps for your convenience. To open a mind map that is not displayed, select the ”Open” icon so you can browse to the location of the mind map. Alternatively, use Finder to open the mind map.
Export Local Mind maps to the Files tab
If you want to “copy” local mind maps, open the local mind map. Next use the main menu “Mind Map” – “Export Mind Map”. Select .smmx and choose the location, for example iCloud Drive. You can now open the mind map from Files. The local mind map can be deleted as it is now a mere copy.
Tip, if you switch clouds it is easiest to simply move all cloud files via Finder.
Note: The AppStore editions are sandboxed. When you open a mind map in the Files tab, adding or opening links to external documents or mind maps is not possible.
