Is this possible?

No, it is not possible to "set" the FileList object , or File object of an input element

An object of this type is returned by the files property of the HTML <input> element; this lets you access the list of files selected with the <input type="file"> element.

var file = document.getElementById('fileItem').files[0];

Method overview

File item(index);
