What Is a .chk File

CHK file.

CHK files are fragments of corrupted files or data on Windows computers, often generated by system corruption, interrupted file transfers, or virus infections.

When Windows detects a problem with a file system on a hard drive or storage device, it automatically runs Check Disk to fix the issue. This process saves corrupted data and files in the Found.000 folder as CHK files.

Can I Delete CHK Files

The FOUND.000 folder with .chk files is usually saved on the device where the error occurred, such as a USB drive if you encountered a problem transferring files from it to your computer. If the CHK files appear on your system drive, they may contain file fragments recovered from the C: drive.

If CHK files are hidden, you can show them in Windows File Explorer to delete them.

Be cautious when planning to delete CHK files, as they can be the only remaining copies of lost data. If your files are secure, you can delete them, but if they're lost and only the CHK files remain, it's best not to delete them.
