CHK File Recovery-Easily Recover CHK Files on Windows 10

Many people may be unfamiliar with CHK files. But in fact, this file type is quite common in Windows computers. It is a file type with the extension .chk.

Why are there CHK files on your computer? Well, many people would like to use CHKDSK command lines or Scandisk utilities to recover lost or corrupted files when they encounter unexpected system problems on a computer. The two approaches effectively fix system errors and recover lost or deleted files. But they also have an inevitable drawback—the recovered files are ended with the .chk extension and cannot be opened or accessed directly.

If you find those inaccessible files on your computer and want to figure out how to recover CHK files to their original formats, this tutorial will help. We’ll share four easy solutions for CHK file recovery on Windows 10 and help you recover valuable data in steps.


What are CHK files?

CHK files are fragmented files that store corrupted or lost data, like videos, images, and other documents, on Windows computers. Those file fragments often ended with a .chk extension. Generally, CHK files are generated by programs like Command Prompt or Scandisk when they handle system errors or corruptions on a hard drive or a storage device. When your computer has system problems caused by interrupted file transfer, improper operation, virus attacks, and more, CHKDSK command lines and Scandisk can be of great help.

After utilities like CHKDSK and Scandisk recover lost data or file fragments, a new folder appears in the computer root drive—Found.000. This Found.000 folder stores those recovered files with a .chk extension. However, those files are not directly readable or accessible. So things become frustrating when those restored files are in front of you, but you can’t reach them. It isn’t easy to differentiate what are their original formats. Therefore, it is necessary to perform CHK file recovery to get the original files.


Four Easy Methods for CHK File Recovery on Windows 10

Are you worried about the above condition? Take it easy! Here are four attainable methods to recover CHK files on Windows 10:

  • 🌈A convenient data recovery tool

After reading, you can easily recover CHK files to their original formats.

Method 2: Changing CHK Extension Manually

You can easily convert CHK files to their original formats by manually changing the file extension. It sounds simple, right? But the problem is, how to identify the original file types of these CHK files?

You can only identify the actual file type by opening them in text editors like Notepad++. After opening a CHK file in Notepad++, you need to check the unrecognizable characters in the header of each file. For example, a file containing “Rar” at the beginning may indicate it is a compressed archive file. Files containing “ID3” may be MP3 files.

📝So there are mainly two steps to change CHK file extensions manually.

Step 1: Open the CHK files in text editors like Notepad++ to identify their original file types.

Step 2: Right-click the CHK file and rename the extension.


Method 3: Modify CHK Extention in Batch

There may be multiple CHK files on your computer. And it is impossible to change their suffix name one by one manually. So you can try Command Prompt to change the extension of CHK files in batch. If you are familiar with CMD lines, you can try the following steps to modify the CHK file extension and recover CHK files from Found.000 folder. Still, it is necessary to identify the original file format before recovery.

📝To modify the CHK file extension in CMD:

chk file recovery in cmd

Step 1: Search CMD in the Windows start menu and select Run as administrator.

Step 2: Type CD/ and press Enter(CD means “change directory”. The slash means “change to the root directory”)

Step 3: Type X: and press Enter. (X means the drive letter which stores the CHK files or the Found.000 folder. For example, E: )

Step 4: Type cd Found.000 and hit Enter.

Step 5: Finally, type ren *.chk *.file extension and hit Enter to convert the CHK files to their original types. (For example, ren *.chk *.jpg )


Method 4: Perform CHK File Recovery via UnCHK

UnCHK can be one of the best CHK data recovery programs. This tool can directly open CHK files and determine if the files are recoverable to video, audio, and other common files. It also helps users retrieve partial files from the .chk files instantly.
