How to open A01 file?

The most common problem when using Split Multi-volume ARJ Compressed Format Archive (part 3) is that a specific A01 is not associated with the program. This is manifested by the fact that A01 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 A01 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 ALZip

An often overlooked issue is to make sure that ALZip is installed on the computer. The easiest method is to use the system search engine by entering the program name ALZip in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file A01 with ALZip. Later in this article you will find a list of programs that can open A01 files.

Step 2. Create association of ALZip with A01 files

If the application is or has been freshly installed, but the A01 file still does not use the ALZip program, it means no association. 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the A01 file with the ALZip program.

Step 3. Update ALZip to the latest version

If, despite the association of the ALZip program with the Split Multi-volume ARJ Compressed Format Archive (part 3) file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the ESTsoft Corp. website and install the latest version.

Step 4. Check for the following problems with the A01 file

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

The A01 file may be unusually small compared to the original file. This suggests truncating the A01 file contents when downloading or copying. 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 A01 or the program directory. Sometimes virus-infected A01 files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the A01 file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged A01 files. The easiest way is to restore the file from a backup, if there is one, or contact ESTsoft
The program indicates that the file is encrypted or corrupted. The encrypted A01 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.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the A01 file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the A01 file for a certain period of time. If this does not work either, restart the device.
