What is a NOTEDB file

NOTEDB files mostly belong to Joplin. NOTEDB files are compressed archives that store note databases. They use the ZIP format to pack a collection of note files, metadata, and attachments into one file.
These files are primarily created by the Joplin application for managing and backing up notes, but a similar approach is used in some Nimbus Note setups.
The contents typically include:

Text files with note content

Metadata and configuration files

Attachments like images and documents

FilExt.com note: While you can open these files with any standard ZIP tool, the best way to view and edit them is to import or open them in Joplin. For more details, please visit Joplin official website.

How do you open NOTEDB files?

You need a suitable software like Joplin to open a NOTEDB 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 NOTEDB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NOTEDB file directly in the browser:. Just drag the file onto this browser window and drop it.

See the previous paragraphs to learn more about the main application. NOTEDB files are often referred to as Joplin databases because this type of file is primarily created or used by this software.
Joplin
A .NOTEDB file is a compressed archive, specifically a ZIP archive, containing a note database used by the Joplin note-taking application. It stores notes, attachments, metadata, and other data related to the user's notes, allowing for backup, portability, and synchronization across devices. The internal structure within the ZIP archive is proprietary to Joplin and conforms to its specific data organization. While the .NOTEDB extension strongly suggests an association with Joplin, it is theoretically possible for other software to utilize the same extension. However, in practice, .NOTEDB files are almost exclusively generated and used by Joplin. This file format is classified as Database File.
