# Check if a file exists

The `Bun.file()` function accepts a path and returns a `BunFile` instance. Use the `.exists()` method to check if a file exists at the given path.

```ts index.ts icon="https://mintcdn.com/bun-1dd33a4e/nIz6GtMH5K-dfXeV/icons/typescript.svg?fit=max&auto=format&n=nIz6GtMH5K-dfXeV&q=85&s=5d73d76daf7eb7b158469d8c30d349b0" theme={"theme":{"light":"github-light","dark":"dracula"}}
const path = "/path/to/package.json";
const file = Bun.file(path);

await file.exists(); // boolean;
```
