Changing default download directory in Chrome Webdriver

I do not have the test setup but passing below as desired_capabilities or extra_capabilities to the constructor should work fine.

'download.default_directory', 'C:\New_Folder'

Snippet (untested):

my $driver = Selenium::Remote::Driver->new(    'browser_name' =>'chrome',    'extra_capabilities' => {        'chromeOptions' => {            'prefs' => {                'download.default_directory' => 'C:\New_Folder'            }        }    });

Edit: Difference between Selenium::Chrome and Selenium::Remote::Driver

Selenium::Chrome allows you to use the ChromeDriver without needing the JRE or a selenium server running. If the ChromeDriver binary is not found, it falls back to the default Selenium::Remote::Driver.

I had troubles understanding the difference mentioned between Selenium::Chrome and Selenium::Remote::Driver. Here's what I got to work:

my $driver = Selenium::Chrome->new(    extra_capabilities => {         'goog:chromeOptions' => {            prefs => {                'download.default_directory' => '/tmp'            },            args => [ 'window-size=1950,500' ]        }    });
