How to open ZNU file?
The most common problem when using ZoneAlarm Mailsafe Renamed is that a specific ZNU is not associated with the program. This causes the file ZNU to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the ZNU 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 ZoneAlarm Pro
In this case, you should first verify that the ZoneAlarm Pro application is installed on the computer. This can be achieved by typing ZoneAlarm Pro into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open ZNU files.
Programs to open ZNU file
Remember to download programs supporting ZNU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of ZoneAlarm Pro with ZNU files
However, it may happen that the application itself does not cause the ZNU file to open in the ZoneAlarm Pro application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the ZNU file with the ZoneAlarm Pro program.
Step 3. Update ZoneAlarm Pro to the latest version
If, despite the association of the ZoneAlarm Pro program with the ZoneAlarm Mailsafe Renamed file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Check Point Software Technologies Ltd. website or update the program from the application.
Step 4. Check for the following problems with the ZNU file
Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:
The ZNU file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ZNU file. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our ZNU file. Sometimes virus-infected ZNU files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the ZNU file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged ZNU files. The easiest way is to restore the file from a backup, if there is one, or contact Check Point Software Technologies Ltd.
When reading, a message appears that the file was encrypted or corrupted. The encrypted ZNU 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. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the ZNU file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the ZNU file for a certain period of time. If the problem persists, restart the machine.
