What Is ARJ?

Before the ZIP file, there was the ARJ. The ARJ was one of the mainstream file archives back in the 1990s. This high-efficiency file archive was developed by Robert Jung, so ARJ actually stands for Archive by Robert Jung. 

Back in the day, when internet speed was lethargic and storage was very limited, ARJ files were used to handle archives that contain more than one file, called multi-volume archives. 

Today’s high-speed downloads and improved technology have rendered them obsolete, but if you ever come across one and accidentally delete it, don’t panic because there are different methods to restore or recover a deleted ARJ file.

How to Recover Deleted ARJ Files

In this article, we’re going to go over how you can recover deleted .arj files on both Windows and Mac.

Method 1: Recover an ARJ File from Windows Recycle Bin

By default, deleted files disappear to the Recycle Bin. As long as you did not empty your Recycle Bin, retrieving your deleted ARJ file from there is easy. Watch out though, because when it gets too full, the Recycle Bin sometimes automatically deletes older files in order to free up some space.

To recover an ARJ file from the Windows Recycle Bin, follow these steps:

  1. Begin by opening the Recycle Bin on your desktop or by clicking the Windows icon on the lower-left side of the screen. 

opening recycle bin

  1. Once the window is open, check to see if your Recycle Bin is empty or not. If there are files inside, then you can resume looking for your ARJ files.
  2. access the deleted file by searching for the keyword or sorting the items by name, date deleted, item type, etc.

  1. Right click the file and then select Restore.

select restore

The file should now be back in its original location. 

Method 2: Recover ARJ File from Mac Trash

If you are using a Mac, Trash is the counterpart to Windows’ Recycle Bin. The steps to recover data from Trash are equally easy. 

Below is your guide to retrieving deleted ARJ files from Trash:

  1. Start by opening Trash from your dock.

  1. Scan through the deleted items and look for the missing file. You can also search for the keyword or file name, and arrange the files by name, date modified, size, and kind.

  1. Right click the file and select Put Back. This will bring the lost file back to its original location.

Method 3: Restore from a Recents Files Folder

Mac’s Recents folder keeps track of Mac’s recent items including apps, files, and servers. If you recently opened or forgot to save an ARJ file type, there’s a big chance that it will be there.

There are two quick and easy ways to access the Recents folder. 

  1. The first thing you can do is open the Finder icon from your dock, then click Recents on the left panel of the window. 

open finder and click recent

All your recent files including unsaved ones will appear here. Browse through the list and open the ARJ file that you need.

  1. The second way is through the Apple icon located on the top-left part of your screen. Click on the icon, and hover to Recent Items. Your recent documents, applications, and servers will appear here.

Method 4: Recover Deleted ARJ with Disk Drill

Disk Drill is one of the solutions that you can use to get back your lost ARJ file. It is one of the most powerful data recovery software available for download. Aside from recovering lost files, it can also protect your data, create byte-to-byte backups, and clean up your Mac. 

If you have completely deleted the file and it’s no longer in the Trash or Recents folder, this software allows users to scan data from your computer, external hard drives (such as USB flash drives), memory cards, and even devices like iPhones, iPods, and Android. Plus, it can retrieve over 400 file types, including our old friend, ARJ. 

The app is available to download for free. However, the free version will only let you retrieve 500MB of data. If you need more than that, an upgrade to the PRO version is available for just $89, or you can take it a step higher by getting the Enterprise version for $499. 

Before you can begin the recovery process, you must first download the Disk Drill app. 

  1. Go to the official website and click Free Download or Upgrade to PRO, whichever option best suits you. This is compatible with OS X 10.6 or later.
