What is a Z3 file

Z3 files mostly belong to ZW3D. The Z3 file extension is used for files with very different internal structures and purposes, depending on their origin.

CAD Files: These Z3 files are linked to ZW3D CAD and also appear as ZWCAD Z3D files. They store 3D modeling and design data used in professional computer-aided design. They are managed by systems from ZWSoft.

Game Data Files: In another use, Z3 files serve as compressed data containers for Infocom interactive fiction. Such files are processed by the Infocom Z-Machine Interpreter, information available at Infocom.

SMT Solver Input Files: A further use is as input files for the Z3 Theorem Prover, which accepts logical formulas for automated reasoning. More details can be found on the Z3 Prover GitHub page.

FilExt.com tip: Check the file origin to select the correct software for opening and viewing the file.

How to open a Z3 file

You need a suitable software like ZW3D to open a Z3 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 Z3 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a Z3 file directly in the browser:. Just drag the file onto this browser window and drop it.
