Choose the folder, not a single note
- Locate the folder in Finder and make a backup if it contains important work.
- Choose File > Open Notes Folder or press Command-Shift-O.
- Select the folder and check the sidebar for the files you expect.
When the folder looks empty
Check the selected path and file extensions. A folder elsewhere on disk is a different folder even if its name matches.
The folder has no MarkThatDown sync account
MarkThatDown does not create a sync account. External synced folders remain subject to the provider’s availability and conflict handling.
