What is an .NB file?

.NB is Mathematica Notebook

An NB file is a structured document created by Mathematica, an application used for mathematical and scientific computation. It contains text, images, audio, functions, and interactive user interface elements. NB files allow mathematical results to be viewed in an interactive document.

Notebook files are saved in a plain text format. Their data is arranged in cells, similar to a standard spreadsheet. Notebooks can be exported to many different file formats, including raster graphic, GIS, compressed, and spreadsheet formats.

NOTE: The "DefaultStyles.nb" file is used as the default style sheet for new notebooks. Notebooks can be opened using the NotebookOpen command within a Mathematica function.
