When creating a page that allows the user to select files and then see a list of the files selected (in html on the page), javascript code can only remove the entire file input, thus removing all files. With single file inputs this is fine, as a remove link can remove the file inputs from the page one by one. The current implementation of multiple file inputs makes this unworkable, as removing the file input removes all of the files and there is no way to remove just one via script. I'd suggest a remove method on the files array or an individual file object.

To be compatible with the w3c FileUpload working draft (http://dev.w3.org/2006/webapi/FileUpload/publish/FileUpload.html#FileList-if), this should be files.removeItem(index).
removeItem was removed from the spec, closing.
