:file Selector
Selects all elements of type file.
.file()
:file is equivalent to [type="file"]. As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $( ":file" ) is equivalent to $("*:file" ), so $( "input:file" ) should be used instead.
Finds all file inputs.
