In the event that a hard drive or an external storage device get corrupted on Windows, we tend to run CHKDSK or Scandisk utility to repair any file system errors. After the repairing process, the corrupted files are usually found to be restored in a Found.000 folder with .chk file extension. Since such CHK files can’t be read, there’s no direct way to know which files have been recovered from our problematic drive.
So here comes the question. How can we open and recover a CHK file? Is it possible to recover data from CHK files? Today we’ll deliver a comprehensive guide for all that you should know about CHK file recovery in Windows.

As mentioned earlier, the files with .chk extension are not readable, so that we are unable to open and access CHK files directly. To make CHK files accessible and recover contents inside these files, the key point is to convert .chk files to their original formats. CHK files might be full files or file fragments. Based on different scenarios, let’s see specific solutions on CHK file recovery in the following.
When CHK files are full files, luckily, we can recover them through changing their file extensions. There are 2 options to achieve it, which can be checked out as below.
This solution would be recommended if you only have one or several CHK files to be recovered, because manually renaming the extensions of multiple files could be pretty time-consuming.
In case you remember the original file format of the .chk data, things are going to be much easier. What we are supposed to do is navigate to Found.000 folder in File Explorer, click View > Show/hide, and make sure File name extensions is chosen. Then change the CHK file extension to its original type, open the file with an associated app to verify if it has been restored successfully.
However, what if you have no idea of the original .chk file extension type? Just identify it at first. Here are our steps in detail:
After identification, you’re allowed to recover the CHK file by simply renaming its extension.
If the CHK files that need to be restored are in a large number and you are exactly an experienced command-line user, this alternative way is made for you. Also, keep in mind that it’s feasible in the condition where all the .chk files were in the same format originally, as CMD will change all existing CHK files to the same file format simultaneously. That said, pursue the steps as follows if you find yourself in the described position.
Supposing the 2 methods introduced above prove to be not working, your .chk files are most likely the file fragments of corrupted data from your storage device. In this case, you may need a dedicated tool to piece them back together. To convert .chk files back to original extensions and recover data from CHK files, see below for the step-by-step tutorials on using 2 pieces of free CHK file recovery software: UnCHK and Chk-Back. Just opt for one of them as you prefer.
Anytime a program or Windows system crashes, there are opening files that remain not closed properly, usually leading to data corruption or even data loss. Although these corrupted or lost data could be stored into Found.000 folder as CHK files after a CHKDSK or Scandisk, it’s frustrating to know that CHK files are not accessible as other normal file formats. Can CHK files be recovered? The answer is certainly positive. You’re suggested to try a trustworthy tool --- Cisdem Data Recovery, which can not only recover CHK files easily, but also restore lost/damaged files without using CHK files.
