What is a ARJ file?
ARJ is a compressed archive format developed for DOS operating system. Older Windows versions (95, 98, 2000) used dedicated ARJ32 format. As is the case with other file archive formats, ARJ file is a data container that stores one or more compressed files.
ARJ uses compression algorithm developed by Robert Jung. Archive containers can be useful for saving disk space and creating backup copies of data. ARJ supports multiple volume archives.

How to open ARJ files
If you cannot open the ARJ file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports ARJ among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ARJ file can be found in the table. Now just download and install the appropriate application.
Possible problems with the ARJ format files
The inability to open and operate the ARJ file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the ARJ Compressed Archive Format file. Below is a list of possible problems.
- Corruption of a ARJ file which is being opened
- Incorrect links to the ARJ file in registry entries.
- Accidental deletion of the description of the ARJ from the Windows registry
- Incomplete installation of an application that supports the ARJ format
- The ARJ file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the ARJ file.
- Drivers of equipment used by the computer to open a ARJ file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ARJ file should operate with your programs without any problem. If the problem with the ARJ file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ARJ file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.ARJ) you have two ways to do it. The first and the easiest one is to right-click on the selected ARJ file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the ARJ file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. ARJ) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
