title: Browser Folder Uploading
body: <p>I would like to be able to have a user upload a folder with all the files and folders inside it and retain the hierarchy to my web app using just the browser.</p>
  
  <p>I have searched and not found how to do this. Everyone says that it is a browser problem and I believe it because there is not browser standard for doing this.</p>
  
  <p>I have found and played with many javascript implementations of uploading files. When I drag a folder onto them I can get the list of all the files, but the folders and hierarchy are all gone. If I use the ones that open a dialog to find a file none of them allow selecting a folder.</p>
  
  <p>So how does Dropbox do it?</p>
  
  <p>I can drag a whole folder onto either Chrome or Safari (on my mac) and both of them will upload the folders and files and retain the hierarchy in dropbox.</p>
  
  <p>Doesn't anyone know how they do that so that I can do the same on my own web app that is browser based?</p>
