Multiple file upload (even folder)

I'm looking for an easy to use (free) "module" that can upload multiple files / folders. It must:

• Support image files
• be user-friendly
• be custom开发者_开发技巧izable

It may be written in:

• RoR (Ruby On Rails)
• Java
• Flash

Thanks in advance.

Have a look here http://jimneath.org/2008/04/17/paperclip-attaching-files-in-rails the article explains how to use Paperclip

Or you could try SWFUpload , a Javascript & Flash solution for file uploads

Uploading multiple files and folders in one go is not supported by HTML, which means that your options are Flash or a Java applet. Ruby on Rails isn't going to help you because it's a server-side framework that generates HTML.
