What is a KMNB file?

KMNB files mostly belong to Keep My Notes. KMNB files are used by the Keep My Notes application as an internal SQL-based database to store your note data.
These files hold structured information such as entries, tables, and metadata that the app uses to keep your notes organized.

Data is stored using SQL formatting.

They are meant for use with the Keep My Notes software.

Direct editing with simple text programs is not recommended.

FilExt.com note: Although you can inspect the internal structure with SQL tools, caution is advised to avoid data corruption.

How can I open a KMNB file?

You need a suitable software like Keep My Notes to open a KMNB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.
