.CH is OS/2 configuration

The ch file extension is associated with the IBM OS/2, an operating system for IBM-PC compatible computers developed by Microsoft and IBM, later only by IBM.

Currently, .CH file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.
