Last Updated on 1 year by William

Whenever you have inquired about the dizzying arrays of tightly interconnected data systems that make up modern-day applications, you may have observed some null files. These files are created by corrupt data that you have encountered on your Windows OS. These files are not easy to open in a simple way. So, how to open these null files? Well, worry not! Because to answer this question we have placed all the possible ways (that we think are the best and worth trying) in this post. Here we will explain how to open the null file.

A third-party Windows program might add a corrupted data file’s .null file extension to identify it as a corrupted data file. This allows a Windows program to provide an alert to a user that the file couldn’t be read.

How To Open Null File

What Are Null Files?

Null files are typically created when a document is opened in a word processing application and the user chooses not to save the changes made to the original document. Null files can also be created when a file is copied and pasted into another application. The .null extension on an encrypted file indicates that it has been encrypted by the Null virus, which is a variant of Stop and Djvu ransomware. The file is encrypted using AES-256 technology, so it is no longer possible to open it by simply changing the extension.

Criminals use this malware when attacking victims, taking the files hostage and requiring the victim to pay the perpetrator to restore access. The program is typically spread through spam emails with malicious file attachments downloaded from the anonymity of users worldwide. Sometimes, these programs are run with the aid of JavaScript.

When the ransomware runs on a user’s computer, it encrypts files on the computer and adds the .null extension onto the names of the files. The targeted files are most often documents, pictures, videos, and backup files, including, .DOCX, .JPG, .MP4, and.DB files

For example, a spreadsheet.xlsx file becomes spreadsheet.xlsx.null.

The Trojan then opens with a window with several tabs displaying concerns about the user’s compromised computer. The tabs display information related to why the computer was infected, how the files were encrypted, the encrypted files, the way to recover the files, and how the user can pay the Bitcoin ransom.

How To Open A Null File?

There are different methods for getting rid of the Null virus, such as Malware bytes Premium software. However, there is no software available that will restore damaged files. To facilitate the recovery of your files, restore them from a previous backup or run a System Restore to a previously infected state.

If you cannot open a file when File Explorer opens it, you may be able to find an application that will open that type of file.

If an OSX application exists that can be used as a NULL file opener, you can choose the “Choose Application…” option in the error box to associate the file extension and open a NULL file in it. 

If you still do not know an application to open a NULL file, try searching for “NULL Wiki”, “application to open NULL file”, or “open NULL file” queries in the search engine you like.

If your file can’t be opened from the Play Store, it may be accessible on other platforms, including Windows and macOS. 

You can try searching online to see if any software application can open the file.
