I have this DOM:
var id = 0; $(\'input:file#upload\')[0].files[ id ]
That get\'s the first file on the 0th index. File properties are list
I' am afraid that you cannot delete objects from FileList object directly. Just assign $('input:file#upload')[0].files to an Array and then remove items from that array using splice or method of your choice and then use that Array.
FileList object
$('input:file#upload')[0].files
Array
splice
