What is cpi file? How to open cpi files?

The cpi file extension is also related to MS-DOS operating system and used for files that contain code page information file.
All versions of MS-DOS and Windows (from DOS 3.3 on), allow you to customize the keyboard mapping - and full screen font characters - to suit different languages.

This type of file is no longer actively used and is most likely obsolete.
