How do I upload multiple files through selenium

Question

I have 4 images in a folder and need to upload all of them together into my application. I have done single file upload through selenium using sendKeys, but the multi file upload is a challenge!

Answer 1

WebElement uploadElement = driver.findElement(By.xpath("   "));
//Single file upload
uploadElement.sendKeys("C:\foldername\abcd.png");

//Multi file upload - simultaneous
uploadElement.sendKeys("C:/foldername/firstImg.png 
 C:/foldername/secondImg.png 
 C:/foldername/thirdImg.png");

Note : needs to be preceeded with space
