I doubt that this is possible, looks like a security risk if you can select files from the clients pc arbitrary to be uploaded. If that would be possible, a malicious website could embed a <input type="file"> in its code, preselect a file from the clients pc, and hide that element with CSS. Most users probably wouldn't notice.
Adding to this I doubt you can reconstruct the full path of the uploaded file, all you get is the filename for what I know.
