What is PNNU file?

This was created by Symantec Corporation.
How to open PNNU file?
The main problem with Norton Utilities is that the PNNU file is incorrectly associated with programs. This is manifested by the fact that PNNU files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the PNNU 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 Norton Utilities
The first step is to check if the computer has the Norton Utilities program installed. The easiest method is to use the system search engine by entering the program name Norton Utilities in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file PNNU with Norton Utilities. Below is a list of programs that support the file PNNU.
Programs to open PNNU file
Remember to download programs supporting PNNU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Norton Utilities with PNNU files
If, despite the installed application, the PNNU file does not start in the Norton Utilities application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the PNNU file with the Norton Utilities application.
Step 3. Update Norton Utilities to the latest version
The fault may also lie with the Norton Utilities program, it is possible that Norton Utilities requires a newer version of the program. In this case, use the Symantec Corporation website or update the program from the application.
Step 4. Check for the following problems with the PNNU file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
The PNNU file may be unusually small compared to the original file. This suggests truncating the PNNU file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our PNNU file. However, remember that not every infected PNNU file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the PNNU files changes over time. 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged PNNU files. The easiest way to restore the file is from a backup or by contacting Symantec Corporation, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted PNNU 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move PNNU to a different directory.
This problem only occurs with more complex files. In this case, the PNNU file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the PNNU file while scanning. If this does not work either, restart the device.
