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. If you cannot open your KMNB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KMNB file directly in the browser:. Just drag the file onto this browser window and drop it.

KMNB file format details:

If you can determine the file format, the associated program can also be determined. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the KMNB files is as follows:

The KMNB file type is primarily used by a single program. The two most common formats are as follows:

• 98% of all KMNB files internally utilize the SQL file format. An SQL file contains a lightweight SQLite database, widely used in application development for storing application related data. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are often between 90 KB and 3 MB in size. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. SQLite format 3. A common filename is 2020-06-01.kmnb. Files like these are sometimes connected to juni.

All other KMNB files (2%) have no uniform format. You can get all the details of your KMNB file by dragging it onto this page or by clicking the button "Choose your .kmnb file to analyze" above.
