What is a NIT file?

NIT files mostly belong to ArcGIS. NIT files are a component of ESRI's ArcGIS system that store indexing data essential for spatial datasets. These files come in several forms:

ArcInfo Coverage Index: This file holds an index for binary raster files, crucial for mapping and rendering data in ArcGIS.

ArcInfo GRID File: Often referred to as an ESRI NIT raster file, it supports the internal structure for managing GRID datasets.

ArcInfo Table Index: This serves as a spatial index file, structuring the spatial relationships within data and enhancing query efficiency.

The NIT files work behind the scenes to maintain and optimize geospatial data performance. They are not meant to be opened directly by users; instead, they serve as an internal reference for software. For more details, visit the ESRI homepage or the ArcGIS Geospatial Platform Overview.

How can I open a NIT file?

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

How to solve problems with NIT files

Associate the NIT file extension with the correct application.
Update your software that should actually open spatial index files. Because only the current version supports the latest NIT file format. Search, therefore, e.g. on the manufacturer website after an available ArcGIS update.
To make sure that your NIT file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
