How to open A03 file?

The most common problem when using Split Multi-volume ARJ Compressed Format Archive (part 5) is that a specific A03 is not associated with the program. Thus, when you open A03, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the A03 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 ARJ32

The first step is to check if the computer has the ARJ32 program installed. This can be achieved by typing ARJ32 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 A03 files.

Programs to open A03 file

Remember to download programs supporting A03 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of ARJ32 with A03 files

If, despite the installed application, the A03 file does not start in the ARJ32 application, you must create a file association. 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. 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. Checking the "Always use the selected program ..." box will permanently associate the A03 file with the ARJ32 program.

Step 3. Update ARJ32 to the latest version

If, however, after binding ARJ32 with Split Multi-volume ARJ Compressed Format Archive (part 5) there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the ARJ Software, Inc. website and install the latest version.

Step 4. Check for the following problems with the A03 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:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the A03 file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file A03 or the program directory. As a result of the scan, sometimes it is not possible to recover A03 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of A03 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular A03 file corruption. The easiest way to restore the file is from a backup or by contacting ARJ Software, Inc., 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 A03 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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 A03 file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the A03 file again. However, some background programs may block the A03 file while scanning. If this does not work either, restart the device.
