If there is an unexpected error in your windows system, the possibility is that you might have used the Scandisk utilities or CHKDSK to find and recover the corrupted files. You are probably here because you can see a file extension that has .chk in the end. The files that have a .chk file extension can only be opened with specific applications.

You can find your .chk files in the folder labeled as FOUND.000 folder in your windows local drive. Each file that is labeled with the .chk extension can’t be accessed directly. But the good thing is, that you can easily recover them using third-party software or following manual instructions.

Before we get down to the CHK file recovery process, it is important to know what CHK files are and why it is necessary to recover them.

What Is A CHK File Extension?

CHK files are fragments of a corrupted file; they can be data, images, or other documents. You can find these types of files in a FOUND folder.

Generally, CHK files are the recovered lost clusters from your windows system. These types of files have the lost contents of files or any documents after abrupt action.

The data which has not been restored properly by the window system will be labeled as “lost file fragments” and will be automatically converted as CHK files.

This type of file usually occurs due to interrupted file transfer, virus attacks, incorrect manual operation, storage device corruption, Scandisk utility, and many more.

How To Detect CHK Files?

Your windows system often experiences issues like interrupted file operation and storage device corruption. If you still physically unplug the external device before the windows system says “safe to remove hardware, ” you experience a sudden application and system crash.

Windows will ask you to scan and fix the issue. And usually, you will run the inbuilt utility CHKDSK, which is available in windows.

After completing the scan and repair procedure, CHKDSK creates a file with the .chk extension in a folder labeled as FOLDER.000. So, CHK files are fragments of corrupted files, data, or other documents on a windows computer.

Why Is It Necessary To Recover CHK Files?

You may face many situations where you will lose or delete CHK files. But, you will need those deleted CHK files at one time or another. After the abrupt action or interrupted file transfer followed by a CHKDSK scan, you might see that you lost a lot of valuable data. Then simply you can go back to the FOUND folder and try to recover the lost data.

For example, you had some files on a USB drive that was connected to your computer, and you removed the drive before the system said: “safe to remove hardware”.

After this, you ran CHKDSK, and it created CHK files. Later, you came to know you are missing some valuable files and you are experiencing issues like the doc file not opening or the USB showing errors, etc.

How to Convert CHK files to Original Content?

The good thing is you can easily convert the CHK files into original content. You can follow the manual way or you can also get help from third-party software that is specialized in converting CHK files into the original. So, let’s get going

Strategy 1: Recognizing the CHK file type

Well, the good thing is you can easily convert CHK files just by converting them to their original extension. But, don’t think that this method is easy to do.

You have to figure out the file type first of all in order to convert the CHK file to its original form. Although you might find it difficult to recognize any character at the beginning of each CHK file, you can use a text editor app like notepad and open these files there.

The unique headers at the beginning of each CHK file will help you to determine the file type. For example, files that contain ID3 at the beginning are the mp3 files. Another file that has RAR at the beginning or closes to the beginning is Winrar files.

Strategy 2: Changing the CHK extension manually

Once you are down with the file identification part, it’s time to change the extension of the CHK file. For instance, if you have identified an mp3 file, you can change the extension to .mp3 and then use an audio or media player and try to open it there,

Strategy 3: Changing the CHK extension using CMD

CMD can be a big help while trying to convert CHK files to the original content. So, how do you recover CHK files through CMD? Let’s get you through a step-by-step guideline, but remember, you need to be very good at using command lines.

  • Step 1: First of all, locate the command prompt in the windows menu and run it as administrator.
  • Step 2: Input CMD and press the enter button in order to change the root directory.
  • Step 3: Next, input the drive letter where all the CHK files are stored and type cd FOUND.000.
  • Step 4: Then, input ren.chk.jpg in order to change the extension to the original format. You can convert a jpg file to any file like .mp3, png, doc, etc.
