jQuery: 5 useful file upload plugins

Following my "ASP: Scripting.FileSystemObject... how to move, copy and delete a file or a folder" post I think that implementing a file management system for example on an Intranet, could be interesting indeed. In the mentioned post, I explained how to manipulate files already uploaded on the server. Now you could ask how to develop an upload system... so here we are.
I gathered 5 interesting jQuery plug-ins that can help us.

Ajax Upload; A file upload script with progress-bar, drag-and-drop

jQuery Multiple File Upload Plugin

jqUploader

Ajax File Upload

uploadify

I don't think you need further explanations from me. I believe that you can choose the plug-in that best suits your needs by visiting the above sites.
Enjoy!
