What is an NG file

NG files mostly belong to Norton Guide. Your NG file may serve different functions based on its origin.
If it comes from a Norton tool, it is a Norton Guide database that stores structured reference data used internally by Norton products.
If the file is part of a clinical application, it is a NeuroGuide EEG data file. This file holds brain wave measurements and is used with specialized EEG analysis software. For more details on NeuroGuide data, visit Applied Neuroscience.
In some cases, a NG file may actually contain image data in the PNG format. Here, the file is a Portable Network Graphics image employed by Microsoft Office. More information can be found at Microsoft Office.
Note: Even though they share the same extension, these files differ in structure and function. It is important to verify the file’s origin before choosing a viewer or editor.
Tips:

Examine file properties to identify its source.

Use Norton software for Norton Guide database files.

Open NeuroGuide EEG files with dedicated EEG analysis tools.

View PNG image files with any standard image viewer.

How do you open NG files?

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

NG file format:

The file format determines how the data is stored in the file. 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. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the NG files:

The NG file extension is not found very often and is used by a few programs, each with its own file format. But the following two file formats are common:

• 25% of all NG files belong to Norton Guide. These files are not plain text files, so they also contain binary data. NG files can be up to 1 MB in size, but are often around 130 KB - 960 KB. This file type was primarily in use more than 20 years ago. Several words can almost always be found in the files, e.g. Copyright and Clipper. The file name ASM.NG or C53G01C.NG is typical for these files. Such files are related to clipper.
• 20% of all NG files use the same file format, which have the signature NeuroGuide. They consist of illegible, cryptic characters. The average file size is 12 MB with most files being between 4 MB and 20 MB in size. The keywords NeuroGuide are typical for these files. The file name case1.ng is characteristic of these files. Files like these are sometimes connected to person-related data.

All other NG files (55%) have no consistent format, frequently e.g. Expert Help hypertext, PNG and MP3. The category is firmware, gauges, marxloaded, gyration, dfwipi, aluta or image. If you want to find out what your NG file contains, drag and drop it onto this page.
