# 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-farm-ad2450b3-transpiler-cache-version-namespa/pVrMBuZvntvIe2NO/icons/typescript.svg?fit=max&auto=format&n=pVrMBuZvntvIe2NO&q=85&s=81fcaf3ac2cead5d758f3588a492f46a" theme={"theme":{"light":"github-light","dark":"dracula"}}
const path = "/path/to/package.json";
const file = Bun.file(path);

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