Uploading Multiple Files

Hi All,
I have to Implement the Multiple File Upload Functionality.
I don't have problem in the Server Side But in the client side I want to dynamically create the Input boxes for Type file and Add the Value for that dynamically using script.
Basically I will have one Input box with type file and I will be adding dynamically these values into dynamically created types.
I am not able to assign the values dynamically Is it possible? not possible?

Thanks and Regards

Not possible; you cannot write the value of a file input box.
