How to open DAT_DEFAULT file?

The main problem with Siemens NX Data Format is that the DAT_DEFAULT file is incorrectly associated with programs. This causes the file DAT_DEFAULT to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DAT_DEFAULT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install NX

In this case, you should first verify that the NX application is installed on the computer. The easiest method is to use the system search engine by entering the program name NX in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support DAT_DEFAULT files.

Step 2. Create association of NX with DAT_DEFAULT files

However, it may happen that the application itself does not cause the DAT_DEFAULT file to open in the NX application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the DAT_DEFAULT file with the NX program.

Step 3. Update NX to the latest version

If, despite the association of the NX program with the Siemens NX Data Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Siemens Product Lifecycle Management Software Inc. website or update the program from the application.

Step 4. Check for the following problems with the DAT_DEFAULT file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to DAT_DEFAULT files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the DAT_DEFAULT file that we want to open. As a result of the scan, sometimes it is not possible to recover DAT_DEFAULT files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the DAT_DEFAULT file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair DAT_DEFAULT file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted DAT_DEFAULT files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the DAT_DEFAULT file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the DAT_DEFAULT file for a certain period of time. If this does not work either, restart the device.
