What is a CPN file

CPN files mostly belong to CPN Tools. Colored Petri Net files are mainly used with CPN Tools to model and simulate concurrent systems. They use an XML structure to capture system elements and behaviors.
These files come in several forms:
  • Petri Net Models: These represent workflow and system simulations and are the most common use.
  • Game Campaign Files: Used by Age of Empires II (Visit Age of Empires) to define campaign missions.
  • Flight Plan Data: Serve as RXP flight plans for simulation software (See CPN Tools).
  • Grim Dawn Campaign Files: Hold mission data for the Grim Dawn game (Grim Dawn).
    • FilExt.com notes: Opening these files depends on their origin. For Petri net models, use CPN Tools. For game data or flight plans, use the corresponding game editor or simulator. Although the XML basis allows opening the file in a text editor, caution and backups are advised.

    How to open CPN files

    You need a suitable software like CPN Tools to open a CPN file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CPN file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CPN file directly in the browser:. Just drag the file onto this browser window and drop it.

    3. CPN Tools (CPN Model File) by CPN Group at the University of Aarhus
      CPN Tools is a tool for editing, simulating and analysing Coloured Petri Nets. The GUI is based on advanced interaction techniques, such as toolglasses, marking menus, and bi-manual interaction. Feedback facilities provide contextual error messages and indicate dependency relationships between net elements. The tool features incremental syntax checking and code generation which take place while a net is being constructed. A fast simulator efficiently handles both untimed and timed nets. Full and partial state spaces can be generated and analysed, and a standard state space report contains information such as boundedness properties and liveness properties. The functionality of the simulation engine and state space facilities are similar to the corresponding components in Design/CPN, which is a widespread tool for Coloured Petri Nets. This file format is classified as XML. Related links: Coloured Petri Nets at the University of Aarhus
    4. Rise of Nations (Campaign File) by Microsoft Corporation
      This file format is classified as Game.
