If you’ve ever looked behind the scenes into the complicated data structures that most modern applications work with, you must have come across some null files. These files are generated by your Windows data that goes corrupt, ending in a ‘null’ file.

In this article, we’re going over what a null file is and how can you open one.

What is a Null file?

Aforementioned, a null file is generated when Windows or application data files go corrupt. There’s also a chance that the null virus has gotten on your system and is corrupting the files instead. 

This is a variant of ransomware originating from the Stop and Dvju ransomware. The virus encrypts the file with 256-bit AKES encryption which means you can’t change the file extension to recover your file.

Since all data on a null file is either destroyed or corrupt, the best you can treat them is by leaving them alone.

How to open null files?

Just because there’s no point opening a null file doesn’t mean you can’t take a look. Here are two ways you can open null files without any external software.

  • Opening the file as a regular file (by double-clicking)
  • Using a text editor such as Notepad.

Opening the file as a regular file by double-clicking

If you try to open a null file by double-clicking it, all you’ll get is the associated Windows System information window. It doesn’t contain any useful data about the file anyway, and hence, you can technically open the file by double-clicking.

Sometimes and on some particular machines, null files might not react to being double-clicked at all as well.

Open Null files using a text editor 

If you really want to see the gibberish that corrupt data look like, follow these steps.

Step 1: Navigate to the directory your null file is saved and right-click it to proceed.
