How do I set a file input element? If it's a text input, I can set the
value property. But this doesn't work with file inputs.

Browser Peculiarities
* Internet Explorer and Netscape do not use the VALUE attribute as the
default contents of the input area. Any default value set via HTML is
not usable via scripting and the DOM as well (hence it is not listed as
'supported' in any of the browsers.) If a user enters text in the field
however, that value is then reachable via the DOM as it normally would
be for a normal INPUT field (via the .value property.) The reason for
this behavior would presumably be to ensure the security/safety of users
against malicious authors. Opera displays the default VALUE attribute
value and submits it as well (although it prompts for confirmation on
submit if you have not altered that value.)
* Netscape 2+ only supports the onChange event handler attribute in
cases where the user enters or modifies text via the text box; if the
"Browse..." button is the only thing used, the event is not fired.
Internet Explorer 4.0+ fires the event in both cases.
* Netscape 4+ allows some Character-level formatting to be applied to
the contents of this form field. These physical formatting elements
(along with virtual formatting elements that are rendered identically,
such as EM and I) apply to this form field: I, U, S, STRIKE, SUB, SUP,
BIG, SMALL, FONT SIZE and FONT FACE.
* Using a READONLY attribute in IE4 and IE5 on this element still allows
a user to invoke the file...open dialog (from the "Browse..." button),
although the text field is not directly editable. In IE5.5 plus, both
the text field AND the file...open dialog are not usable.
* Opera 5/6: Using the DISABLED attribute still sends the name/value
pair for the element to the form processing script. It should not do this.
