.XNF File

The xnf file extension is used for Extensible Numerical file format.

An xnf file consists in one or several raw data files, with possibly various formats, and some metadata to describe the contents of the data files, stored in a specific XML file.

On a Mac, an xnf file is a bundle, a special kind of folder which looks like a file (and that Finder names a "package"). Double-clicking an *.xnf  file opens a user interface in Smile to browse, view, extract, and plot the data that it contains. On other platforms, an XNF file shows like a regular directory containing the data files and the XML metadata file.

SmileLab 3.2 provides commands to write and read those structures to and from XNF files.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .xnf file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
