Did your computer fail to open a CHK file? We explain what they are used for and recommend software that we know can open or otherwise handle your .CHK files.
What is a CHK file?
The .chk file extension is most commonly associated with the Sophos Anti-Virus software application. The CHK files that are used by the software contain database files that reference different software reporting features and configuration settings.
The .chk file extension is also associated with Windows file fragments. These file fragments are fragments of files that have been cleaned from the hard drive by the ScanDisk or CHKDISK disk checking applications.
The ScanDisk and CHKDISK checking applications are run by the Windows operating system to find errors that may be located on the hard drive. These errors are then written out as CHK files. Oftentimes these files can be removed, as the information contained within them is also stored elsewhere on the user's computer.
