How do i change the location where my file gets downloaded in Selenium Webdriver and firefox driver

Question

I'm trying to save an image using 'save as' option to a particular folder. I found a way to right click on that image, but the problem is, after getting the popup to save the file, i'm not able to set the path where to sava it to. Plz help.

The code for Firefox is:-

public class practice {

 public void pic() throws AWTException{
     WebDriver driver;

     //Proxy Setting     
        FirefoxProfile profile = new FirefoxProfile();
        profile.setAssumeUntrustedCertificateIssuer(false);
        profile.setEnableNativeEvents(false);
        profile.setPreference("network.proxy.type", 1);
        profile.setPreference("network.proxy.http", "localHost");
        profile.setPreference("newtwork.proxy.http_port",3128);

        //Download setting
        profile.setPreference("browser.download.folderlist", 2);
        profile.setPreference("browser.helperapps.neverAsk.saveToDisk","jpeg");
        profile.setPreference("browser.download.dir", "C:\\Users\\Admin\\Desktop\\ScreenShot\\pic.jpeg");
        driver = new FirefoxDriver(profile);

        driver.navigate().to("https://edureka.co/");
        driver.findElement(By.xpath("//*[@id='large-user-info']/div[1]/div[1]/a/div/img"));
        Actions action = new Actions(driver);
        action.moveToElement(driver.findElement(By.xpath("//*[@id='large-user-info']/div[1]/div[1]/a/div/img"))).perform();
        action.contextClick().perform();
        Robot robo = new Robot();
        robo.keyPress(KeyEvent.VK_V);
        robo.keyRelease(KeyEvent.VK_V);
    // Here i am getting the os window but don't know how to send the desired location
    }//method   
}//class

There are a couple of errors there. First set your preferences like this without the image name and format:

profile.setPreference("browser.download.dir", "C:\\Users\\Admin\\Desktop\\ScreenShot\\");

Then if at all your using: browser.download.folderlist, then its wrong usgae. Should be like this (L caps in folderList):
browser.download.folderList

After that,  use then Robot class for desired operations.
