Topic: html4 and addFile function

Hello.
I would like to use addFile function on html4 mode (I'm using successfully on html5).
Quoting the following link:
http://www.plupload.com/punbb/viewtopic.php?id=3654

But this is only possible in html5 runtime and Plupload 2.

Is that still valid, and there isn't a straightforward way to addFile with html4?

Thanks
