What is a NDF file?
NDF is a secondary database file used along with primary MDF files. If primary file becomes too large or not enough disk space is available (on HDD, SSD, or given partition), a NDF file is automatically created in chosen disk location and the data is distributed between primary and secondary files.
Microsoft SQL Server NDF files are dependent on MDF database files. NDF file can also be manually created by user if the SQL data structure needs to be divided.

How to open NDF files
If you cannot open the NDF file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports NDF among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the NDF file can be found in the table. Now just download and install the appropriate application.
Possible problems with the NDF format files
The inability to open and operate the NDF file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft SQL Server Secondary Data Format file. Below is a list of possible problems.
- Corruption of a NDF file which is being opened
- Incorrect links to the NDF file in registry entries.
- Accidental deletion of the description of the NDF from the Windows registry
- Incomplete installation of an application that supports the NDF format
- The NDF file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the NDF file.
- Drivers of equipment used by the computer to open a NDF file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the NDF file should operate with your programs without any problem. If the problem with the NDF file has not been solved, it may be due to the fact that in this case there is also another rare problem with the NDF file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.NDF) you have two ways to do it. The first and the easiest one is to right-click on the selected NDF file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the NDF file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. NDF) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
