title: Why are Multiple File Uploads not Simple without Flash/.NET?
body: <p>The only tools/plugins I've seen online that allow for multiple files to be selected for upload through one single dialog box using a SHIFT or CTRL click action (as opposed to clicking on a single file per  for file uploads) exist for controls made in Flash/.NET/Java, not just straight Javascript/HTML/PHP.</p>
  
  <p>Why is that the case?  I'd imagine that if possible, site developers would look to having less dependencies on different technologies rather than more.</p>
