Backend file upload form

[punkstjimmy]

Hi,

does anyone know where this is generated from?

I'm trying to replace the upload form in the file manager with a HTML5 drag and drop uploader. I can't work out where Contao is loading this form from. I need to replace the default backend upload widget with my custom one.

There seems to be no reference to it in the tl_files.php DCA file.

This is the URL Contao uses to display the form:

main.php?do=files&act=move&mode=2&pid=files

There's no 'move' action in the tl_files DCA though? Any ideas where Contao creates and outputs the uploader widget?

Thanks
