.CPB File

The cpb file extension seems to be mainly associated with the Comicino Studio, a rapid development environment for desktop and mobile applications.

The cpb file contains saved source code and other data that can be compiled to final application.

Files with cpb file extension can be mostly found as projects made using Comicino Studio development environment.

How to open:

Use Comicino Studio to open and continue to work with .cpb project files.

How to convert:

Maybe some sort of export is possible using Comicino Studio, but other than that, a direct conversion of cpb files seems unlikely.
