How to set a value to a file input in HTML to a client side disk file system path?

by

You cannot set it to a client side disk file system path, due to security reasons.

Imagine:

<form name="foo" method="post" enctype="multipart/form-data">
    <input type="file" value="c:/passwords.txt">
</form>
<script>document.foo.submit();</script>

You don’t want the websites you visit to be able to do this, do you? =)

You can only set it to a publicly accessible web resource as seen in this answer, but this is clearly not the same as a client side disk file system path and it’s therefore useless in that context.
