Understanding CPI Files and How to Open Them

CPI files are not commonly known file types, and they can be associated with multiple applications and purposes. While they are not as widely encountered as more common file types like .PDF, .DOCX, or .JPG, understanding what CPI files are and how to open them can be valuable. In this article, we will explore CPI files, their potential uses, and methods to open them.

CPI files are associated with a few different applications and contexts. The meaning and function of a CPI file can vary, but here are some common uses:
