CPI files: Frequently Asked Questions
What are CPI files?
The CPI extension is associated with vector files generated by Calamus, a desktop publishing software that was launched in the late 1980s. At the time, Calamus was created exclusively for the Atari ST - an innovative series of home computers. Moreover, Calamus was amongst the earliest vector handling programs that provided support for virtual objects and frames, in addition to its own proprietary vector formats. Over the years, Calamus has received several updates, with the most recent one being Calamus SL2006.
