What is a(n) ARJ file?
ARJ (ARJ Compressed Format Archive) is a file format used for data compression and archiving. It was developed in the late 1980s by Robert Jung and is considered the most popular data compression format on MS-DOS computers. ARJ files typically have a .ARJ extension. ARJ supports the compression of multiple files into a single archive using a lossless data compression algorithm.
Using ARJ, you can also control the level of compression, manage subdirectories and store comments in the file headers. The comments provide information about the content stored within the archive and help users to quickly identify which files are stored in it.
How to open ARJ file?
There could be multiple reasons for which the system does not support given file. In the case of ARJ extension, it is probable that none of the installed programs support given file type. Therefore, user should undertake the following steps
Step 1: Install a program that supports ARJ files
If an application that supports ARJ files is installed on user’s system, but is not used to open such files by default, right-click on the file icon and choose "Open with" option from the menu. Next, select the proper application and check the "Always use the selected application to open this kind of files" box. The system will store this information in its registry and use the selected program to open files with ARJ extension by default.
Hint for Mac OS users
For Mac OS users the procedure is analogous – open the file menu by right-clicking on the ARJ file and choose "Information" option and select "Open with program" option. From the submenu select an application and click on "Change all" button.
Step 2: Find and download proper software
Inability to open ARJ files may also be related to the lack of any application that supports given file being installed on the system. Should that be the case, user needs to download and install one of the following applications. Once installed, the system will automatically associate newly installed application with ARJ files. If this step fails, see step 1.

Step 3: Check the ARJ file for errors
Sometimes, although relatively rarely, steps 1 and 2 might not lead to expected results. There can be several reasons for such situation to occur:
- ARJ file has been downloaded from the internet but for some reason it is incomplete. In such case the file should be re-downloaded and opened again.
- Structure of given ARJ file could be corrupted and as such the program is not able to open the file
- Storage medium on which the file was stored is damaged
- It is important to ascertain that the icon representing given file is not a shortcut a related ARJ file no longer present in the location to which the shortcut points
- If the user account has restricted access privileges it is advised to contact the system administrator or an IT expert
