As far as I can see in the source code of the File Upload Class, I see in this piece of source code:
Code:
function set_allowed_types($types)
{
$this->allowed_types = explode('|', $types);
}
that the function expects a string with a pipe, so I don't think a wild-card (*) will do the trick.
The only solution I can think of, is just add as much file types as you can imagine. Or you have to modify / extend the class.
