Notes about the CHK file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The CHK file type is primarily associated with 'CHKDSK/SCANDISK Output'. File fragments cleaned from the disk. When you run the DOS or Windows disk checking programs they can find errors and may write these out as file fragments in .CHK files. Often these can be deleted as the information is elsewhere on your hard disk. Sometimes, however, you need to recover information from a .CHK file (or files). Use UnCHK and/or FileCHK to help you do this.
