# 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-dc5e99a7-serve-route-target-normalization/irnPaIf5BInKUovc/icons/typescript.svg?fit=max&auto=format&n=irnPaIf5BInKUovc&q=85&s=749f5ca3fc8733d63266eddb19569000" theme={null}
const path = "/path/to/package.json";
const file = Bun.file(path);

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