public class Downloading_File {

/**

*/
public static void main(String[] args) {
FirefoxProfile profile = new FirefoxProfile();

profile.setPreference("browser.download.folderList", 2);

profile.setPreference("browser.download.dir","C:\\Users\\Admin\\Downloads");
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/msword,application/x-rar-compressed,application/octet-stream,application/csv,text/csv");

WebDriver driver = new FirefoxDriver(profile);
driver.get("http://qtpselenium.com/test/testdownload.php");
driver.findElement(By.xpath("html/body/a[1]")).click();
// driver.findElement(By.xpath("html/body/a[2]")).click();
