CHK files are fragmented files produced by Chkdsk or Scandisk in Windows to save corrupted data. If you have loads of .chk files in the found.000 folder, here are four ways on how to recover CHK files using manual methods, CMD command, professional CHK file recovery full version software, and tools.

What Is a .chk File

CHK file.

A CHK file is fragments of corrupted files, data, images, or other documents with .chk file extension on Windows computers. Usually, CHK files are generated by the Windows system due to hard drive or storage device corruption, interrupted file transferring, improper operations, virus infection, and so on.

When the Windows system detects a problem with a file system on a hard drive or storage device, it automatically runs Check Disk to fix the file system. After this, Windows creates a Found.000 folder, saving all fragments of corrupted data and files as CHK files there.

Can I Delete CHK Files

Yes. Most of the time, the FOUND.000 folder with .chk files is saved on the save device where the error occurred. For example, if you encountered a problem while transferring files from USB to your computer, you may find a Found.000 folder with CHK files. If you find CHK files appear on your system drive, it may contain some file fragments recovered from the C: drive. 

Note that sometimes the CHK files may be hidden. You can use Windows File Explorer to show hidden files and delete these hidden CHK files.

However, be careful when you plan to delete the CHK files. If your files and data are secure, you may delete them from your device. But, if your files are lost, and only these CHK files exist on your drive, don't delete them.
