How to open a .zig file (Windows, Mac, Linux)

Q: Why can't I open my .zig file?

Usually your computer lacks an app that understands Zig. Install one of the apps listed here, or convert the file to a more common format.

A .zig file is a Zig Source File. If double-clicking does nothing, your computer simply does not have an app that reads Zig yet. Here is how to fix that on each operating system, using free software wherever possible.

Open a .zig file step by step

Confirm the file really is a .zig. Drop it into the WhatFileType file identifier, which reads its signature without uploading anything.
On Windows, open it with VS Code (Zig extension) or any text editor.
On Mac, use VS Code (Zig extension) or any text editor.
On Linux, try VS Code (Zig extension) or any text editor.
Still stuck? Convert the .zig to exe (compiled), which opens more widely.

Before you open it: Caution. A .zig file is program source. Compiling and running it executes its code; review unfamiliar files first.

Frequently asked questions

Why can't I open my .zig file?

Almost always because no installed app understands Zig. Install one of the apps above, or convert the file to a format your existing software already reads.

How do I run a .zig file?

Install Zig and run zig run file.zig, or zig build in a project with a build.zig file. The same binary cross-compiles for other platforms.

Is Zig a replacement for C or for Rust?

For C, mostly. Zig keeps manual memory management and C-level simplicity, while Rust enforces memory safety through its borrow checker. They solve overlapping problems differently.
