title: Selenium WebDriver: Upload multiple files
body: <p>My test need to upload test files in different browsers (I use <code>WebDriver</code> + <code>Java</code>). 
  For a single file upload, everything works fine. I just send the path </p>
  
  <pre><code>"C:\\testdata\\testfile.txt"
  But, syntax changes for multiple upload and different browsers.
  
  (
  IE: 
  "\"" + "C:\\Selenium\\TestData\\Flexy - BigFile1.txt"+"\"" +"\""+"C:\\Selenium\\TestData\\Flexy - BigFile2.txt" + "\""
  
  CHROME: 
  "C:\\Selenium\\TestData\\Flexy - BigFile1.txt"+"\n"+"C:\\Selenium\\TestData\\Flexy - BigFile2.txt".
  </code></pre>
  
  <p>Firefox: I'm not able to find a correct syntax. </p>
  
  <p>Any idea? </p>
  
  <p>Is there a common syntax for all browsers?</p>
