Selenium2Library handles only things that happen inside browser. You should use OperatingSystem library to check that file exists on disk. Maybe use "File Should Exist" keyword – Pekka
Thank you @Pekka , Any possibility to give auto-download option in browser to particular directory – Auto-learner
Can i know File Should Exist keyword is platform independent or not ? My tests need to execute on Linux and windows platforms – Auto-learner
code that i am trying is as follows,please let me know what is wrong in that ${preferences} = Create Dictionary browser.download.folderList = 2 browser.download.dir = C:/Users/mra001/Downloads/Cambium_Builds open browser ${cnMaestro_URL} ${Browser} desired_capabilities=${preferences} – Auto-learner
Unfortunately Selenium2Library Open Browser keyword documentation says you can use desired_capabilities only if you are using a remote server. This would explain why your code does not work. I think a workaround is to create a new firefox profile and load it with ff_profile_dir parameter. Check Firefox profiles from here: support.mozilla.org/en-US/kb/… – Pekka

In chrome I open the chrome://downloads page and then retrieve the downloaded files list from shadow DOM like this:

const docs = document
  .querySelector('downloads-manager')
  .shadowRoot.querySelector('#downloads-list')
  .getElementsByTagName('downloads-item');

This solution is restrained to chrome, the data also contains information like file path and download date.

Check out this link - http://ardesco.lazerycode.com/testing/webdriver/2012/07/25/how-to-download-files-with-selenium-and-why-you-shouldnt.html

Also, here's how you can auto-download the file to a particular directory - 

FirefoxProfile profile = new FirefoxProfile();
profile.SetPreference("browser.download.folderList",2);
profile.SetPreference("browser.download.dir", @"c:\path\to\downloads \folder");   
FirefoxDriver driver = new FirefoxDriver(profile);

u can use following python function to download file without showing dialog box.

Also u can set preference for which type of files save file dialog box should not get displayed.

def create_profile():
    from selenium import webdriver
    fp =webdriver.FirefoxProfile()
    fp.set_preference("browser.download.folderList",2)
    fp.set_preference("browser.download.manager.showWhenStarting",False)
    fp.set_preference("browser.download.dir",'C:/Users/mra001/Downloads/Cambium_Builds')
    fp.set_preference("browser.helperApps.neverAsk.saveToDisk",'text/csv/xls')
    fp.update_preferences()
    return fp.path
