The answer is simples: the input[type='file'] don't have the "value"
propertie. It's a security question... Realize that you enter a site
and this site has a input[type='file'] in a hidden (position:
absolute; top: -10000;). In the case of you could change the "value"
property for a input[type='file'], you would be able to get files from
the guest's PC without his permission. You would be able to change the
"value" to any value and, if the path you set (i.e.:
c:\windows\php.ini) exists in the guest's PC, the file would be sent
to the server. Got it?
You can do a simple "document.forms['formname'].reset()" to solve
your problem.
