If you've ever encountered an unexpected error on your Windows system, it's quite possible that you might have used the CHKDSK or Scandisk utilities to find and recover corrupted files. While both these Windows utilities are great to repair and recover lost files due to a system error, they have one major drawback. Each recovered file is saved with a .CHK extension and you won't be able to access it directly. These files are generally stored in the Found.000 folder in your Windows local drive.
If you're also seeing the same .CHK files on your PC, this guide will help. Today, we'll give away the best recovery solutions to recover chk files in Windows 10 and retrieve your valuable data.
CHK Files are fragmented files that store fragments of corrupted files that are recovered by CHKDSK or Scandisk utilities. As we mentioned earlier, these files are stored inside the Found.000 folder that you can find in the root drive.
As soon as you run any of the above-mentioned utilities, they automatically look for corrupted/lost data during a system error, create their fragments, and store the resulted files in the Found.000 folder with a .CHK extension. However, since these files aren't readable, it becomes quite frustrating as you'll never know which files were recovered by CHKDSK/Scandisk.
The answer is Yes! There aren't any restrictions imposed by the Windows system on CHK files. If you are 100% sure that all your important data is safe, you can go ahead and remove these .CHK files without any second thoughts. However, if you are not sure about the data loss, it would be better to first recover .CHK files.
If you mistakenly deleted the CHK files or the files are missing due to system crash, try Recoverit data recovery to restore the lost files. It’s the most effective and efficient way to recover CHK files with Wondershare Recoverit. The tool will let you directly scan the original location from where the files were deleted. This way you'll be able to recover the original data without having to open the CHK files. The best part about using Recoverit is that it can recover different file types.

You can easily recover .CHK files by converting them to their original extension. But, this method isn't as simple as it sounds. In order to convert a file to the original extension, you'll have to first identify the file type. In general, you'll see unrecognizable characters at the beginning of each .CHK file. You can open these .chk files with any text editor like Notepad++.
If you look closely, you may find some unique headers that'll let you determine the file type. For instance, files that contain .Rar! at the or close to the beginning are Winrar archives. Similarly, files that have ID3 in their header are mp3 files. So, check the header of the .CHk file and you'll be able to identify its type easily.
Once you have identified the original file type, you can easily change the extension of the .CHK file. For example, if you have identified it's a MP4 files, you can change its extension to .mp4 and then use a video player to try to open it.
If there are quite a few CHK files, you can also use Command Prompt to change .CHK files extension in batch. However, you should only proceed with this method if you have worked on CMD before as one small blunder can even cause permanent data loss. So, if you are an experienced administrator, follow these steps to recover CHK files using command prompt.

It's probably the easiest way to recover CHK files as you won't have to perform any critical tasks. With a single-click, UnCHK will automatically scan your drive and recover the .chk files instantly.

CHK-Mate also recognizes up to 20 different types of files although you can also add more if you need to.
