What is an ARJ File and How to Open an ARJ File

We often come across different file formats like ZIP and RAR or ARJ, which is less common. I Have you ever come across an ARJ file, wondering what it actually is and how to open it? You are not the only one. ARJ files were once a popular choice for compressing and archiving data. As new formats started coming into play, ARJ files started losing popularity. But they have not become obsolete and are still in use. This guide aims to help you understand what ARJ files are and how to open ARJ files easily.

Part 1: What is an ARJ File

In the early 90s, Robert Jung developed the ARJ compressed file format. The abbreviation ARJ comes from Archived by Robert Jung, which happens to be the name of its developer. The ARJ files became popular due to their ability to create multi-volume archives on the early Windows systems. Despite many other compressed file formats becoming available, the ARJ file format is still relevant and supported by various archiving tools.

Features of ARJ Files:

ARJ files have various notable features:

• • High Compression Ratio: ARJ files are relatively smaller in size than other file formats due to advanced compression techniques.
• • Multi-Volume Archiving: One unique and widely used feature of ARJ files is their ability to generate multi-volume archives. This allows large files to be broken down into small files to create split archives.
• • Recovery Records: Files created in the ARJ format have a recovery record that helps restore the corrupted files.

What are ARJ Files Used For:

Following are some common uses of ARJ files:

1. ARJ files are used to transfer files and data from one system to another. As these files provide a high compression ratio, the transfer function becomes easier and more manageable through ARJ files.
2. ARJ files are used to create a single backup file that effectively backs up your computer's data. It not only secures your precious data but also occupies less disk storage.
3. ARJ files were also commonly used by developers to distribute software packages efficiently without compromising the transfer quality.
4. Some older applications still use ARJ file format to ensure compatibility and preserve their historical data.
