Open CHK File

Files with the CHK extension are fragments of files that are created in Microsoft Windows and contain data associated with a file that has been deleted, lost, or has changed location on the storage medium.

There is an applet built into most versions of Microsoft Windows that is used to find and delete lost and unused files, which have been created by the system, and it can also locate files with the CHK extension and delete them. These files typically have of no practical utility as the original files have been deleted or moved by users to another directory.

There are third-party applications developed to open and view the content of these CHK files in case you need to view or retrieve their content, for example the CHK-Mate software.

There is also the FileCHK program and the UnCHK software developed to provide functionalities for recovering or restoring the data contained in a CHK file.
