How to open A20 file?

The main problem with Split Multi-volume ARJ Compressed Format Archive (part 22) is that the A20 file is incorrectly associated with programs. This causes the file A20 to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the A20 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

An often overlooked issue is to make sure that ARJ32 is installed on the computer. This can be achieved by typing ARJ32 into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file A20.

Programs to open A20 file

Remember to download programs supporting A20 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of ARJ32 with A20 files

However, it may happen that the application itself does not cause the A20 file to open in the ARJ32 application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. 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. 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 A20 file with the ARJ32 application.

Step 3. Update ARJ32 to the latest version

If, however, after binding ARJ32 with Split Multi-volume ARJ Compressed Format Archive (part 22) 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 A20 file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to A20 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. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file A20 or the program directory. As a result of the scan, sometimes it is not possible to recover A20 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of A20 file may not always be supported by the latest software version. 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. Sometimes the program itself has options to repair the most popular A20 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.
The program can also signal the fact of encryption. The encrypted A20 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. Copying the A20 file to another location will fix the problem.
This problem usually affects more complex files. In this case, the A20 file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the A20 file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
