# class: Download

[Download] objects are dispatched by page via the [`event: Page.download`] event.

All the downloaded files belonging to the browser context are deleted when the browser context is closed. All downloaded
files are deleted when the browser closes.

Download event is emitted once the download starts. Download path becomes available once download completes:

```js
const [ download ] = await Promise.all([
  page.waitForEvent('download'), // wait for download to start
  page.click('a')
]);
// wait for download to complete
const path = await download.path();
...
```

> **NOTE** Browser context **must** be created with the `acceptDownloads` set to `true` when user needs access to the
downloaded content. If `acceptDownloads` is not set or set to `false`, download events are emitted, but the actual
download is not performed and user has no access to the downloaded files.

## method: Download.suggestedFilename
- returns: <[string]>

Returns suggested filename for this download. It is typically computed by the browser from the

or the `download` attribute. See the spec on [whatwg](https://html.spec.whatwg.org/#downloading-resources). Different
browsers can use different logic for computing it.
