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
  2. 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.
  3. access the deleted file by searching for the keyword or sorting the items by name, date deleted, item type, etc.searching keyword
  4. 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.opening trash
  2. 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.look for the missing file

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.
