Last month I mentioned an app written by Ryan Favro demonstrating how to use Flex 2 to build a client that allows you to upload multiple files to ColdFusion. Well, Ryan has now written an article about his app for Dev Center. If you want to learn more about how his code works, check this out.

One of the sulutions to select at once and upload multiple files or all files within folder is Flash upload control. It works in all browsers and OSs and just needs Flash player on client side.
See example here:

Take a look to another advanced flash upload utility EAFlashUpload:
