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. Changes can be made using the "Change" button. 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.

Step 4. Check for the following problems with the ZO3 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to ZO3 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. However, it is important to scan the entire system, not only the file ZO3 or the program directory. As a result of the scan, sometimes it is not possible to recover ZO3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the ZO3 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair ZO3 file corruption. You can restore the file from a backup or use Check Point Software Technologies Ltd. help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted ZO3 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. If possible, you can try to move the ZO3 file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file ZO3 to close. Some anti-virus or backup software may occupy the ZO3 file for a certain period of time. If the problem persists, restart the machine.
