What is a CNX file?

CNX files mostly belong to Kneura TutorPlus. CNX files come in different variants. The most common are Kneura Canvas files, which use XML to store canvas learning content for systems like Kneura TutorPlus and Kneura Teach. These files hold structured data for interactive educational modules and can be opened with an XML editor or the native e-learning application.
Another variant is an XML data file produced by WinWerth. These files are plain XML that hold general structured content. For more on this, visit the WinWerth website.
A third, less common type is a GMP graphics file from GMPlayer. In this case the CNX file contains game sprite information used in game development.
Key details provided by FilExt.com:

Kneura Canvas files: Store educational module data in XML format.

XML data files: Hold structured data for various applications.

GMP graphics files: Contain game sprite graphics.

FilExt.com tip: You can view XML content with a simple text editor, but using the dedicated software offers a better experience.
