<PolicyExample policy="DefaultDownloadDirectory" />

## Values

`DefaultDownloadDirectory` expects a path to the directory downloads are saved to, such as `/Users/username/Documents`.
The user can still change it.

- `${home}` expands to the user's home directory, so `${home}/Downloads` works across profiles and platforms.

<PolicyExample policy="DisableBuiltinPDFViewer" />

## Values

- Set to `true` to hand PDF files to the operating system's default PDF handler.
- Set to `false` to open PDF files in Firefox. Unlike most policies, this actively sets the handler back to the built-in viewer rather than doing nothing.

If the [`Handlers`](/reference/policies/handlers/) policy already configures `application/pdf` or the `pdf` extension, that policy wins and `DisableBuiltinPDFViewer` is ignored.
