CHK File Recovery Methods

In my article, I will discuss various CHK file recovery methods.

What Are CHK Files and Their Origin?

CHK files are fragments of files that are created when the CHKDSK utility is used to scan and repair disk errors. These files are usually found in the FOUND.000 directory and have generic names such as File0000.chk.

The origin of CHK files can be traced back to the Windows operating system, where they are generated as a result of system interruptions, power outages, or crashes. When a file system error occurs, CHKDSK automatically creates these fragments as a way to recover data.

To recover data from CHK files, you can try using a data recovery tool like Disk Drill or a hex editor to manually extract information. Another method is to rename the CHK files with the appropriate file extension based on their original format, such as .jpg for JPEG images or .mp3 for MP3 audio files.

Is It Safe to Delete These Files?

When it comes to CHK files, it is generally safe to delete them once you have recovered the original files. These CHK files are usually temporary files created by disk check programs or utilities like Disk Drill when trying to recover lost data. They are not necessary once the original files have been restored.

However, before deleting any CHK files, it is important to double-check that you have successfully recovered all the important data. Make sure to open and review each file to ensure that nothing is missing or corrupted.

If you are unsure about the contents of the CHK files, you can also use a text editor or a hex editor to open them and see if they contain any important data. This way, you can determine if it is safe to delete them or if they need to be further analyzed or recovered.

Identifying the Correct File Extension

Manual Extension Change for Recovery

A manual extension tool

For manual extension change in CHK file recovery, follow these steps:

First, locate the CHK files you want to recover on your computer.

Next, right-click on the file and select “Rename.”

Change the file extension from .CHK to the original file format extension. For example, if it was a Word document, change the extension to .docx.

After changing the extension, double-click on the file to see if you can open it in the appropriate program.

If the file opens successfully, you have recovered the data from the CHK file. If not, you may need to try a different data recovery method.

Using Recovery Tools for CHK Files

Another tool that can be used for CHK file recovery is WinRAR. To recover CHK files using WinRAR, simply open the program and navigate to the location of the CHK files. Right-click on the file and select “Extract to” to extract the contents of the CHK file.

If the above methods do not work, there are specialized file recovery tools available for download that can help with CHK file recovery. One such tool is Recuva, which is a free data recovery software that can recover deleted files from hard drives, memory cards, and other storage devices.

By using these recovery tools, you may be able to successfully recover your CHK files and prevent data loss.

Recovering Files Without Using CHK

To recover files without using CHK, you can try using a different method. One way to do this is by utilizing a data recovery software. Download a reputable data recovery program such as Recuva or Disk Drill to help you retrieve your lost files. These programs can scan your computer’s storage and locate the deleted files that you are trying to recover.

Once you have downloaded the software, install it on your computer and follow the on-screen instructions to begin the scanning process. Make sure to select the appropriate drive where your files were deleted and let the software scan for any recoverable data.

After the scan is complete, the program will display a list of files that can be recovered. Select the files you want to restore and choose a safe location to save them. Avoid saving the recovered files in the same location where they were originally deleted to prevent any data overwriting.

Utilizing MiniTool for File Recovery

When using MiniTool for CHK file recovery, start by launching the software and selecting “Undelete Recovery” from the main interface. This option is ideal for recovering recently deleted files. Choose the drive where the CHK files were located and click “Scan” to initiate the scanning process. MiniTool will search for all deleted files on the selected drive.

Once the scan is complete, browse through the list of recoverable files and select the CHK files you want to restore. Click “Recover” and choose a safe location to save the recovered files. It is recommended to save the files to a different drive to avoid overwriting any data.

After the recovery process is finished, check the destination folder to ensure that the CHK files have been successfully recovered. Open and verify the files to confirm that they are intact and accessible. If any files are corrupted or cannot be opened, you can try running a deep scan using MiniTool for better results.
