What is a ZEN file?

ZEN files mostly belong to Zenon Logic Simulator.

Zenon Logic Files: ZEN files are used as project data files in the Zenon Logic Simulator. They store control logic settings and project details. Some files are also known as Zelio Soft project files or work with ZEN-ON Z-Sequencer in industrial automation setups.

Gothic Game Archives: In other cases, ZEN files contain save game data for Gothic II. They archive game progress and configuration data used by the Gothic game engine. For more details, check out the Gothic official page.

They use proprietary internal structures.
Each use case requires its own dedicated software.
Back up your files before making any changes.

FilExt.com tip: Remember that despite sharing the same extension, these files serve different purposes. Use the Zenon Logic Simulator for control projects and Gothic II for game archives.
