The behavior of <input type="file"> elements is very strictly controlled by browsers, and you cannot force them to do anything other than what they want to do. Generally, modern browsers will only allow a file picker to be used for selecting a file for upload. Your Javascript code can't set the value and can't see anything more than the tail file name (the name without prefixing directory names).
