[Plugin: Contact Form 7] Not able to attach a file

Can they make a fix to the plugin to allow me to attach a pdf with my email response.

I see a complicated / undynamic solution here: http://wordpress.org/support/topic/contact-form-7-sending-attachments-without-user-upload

I want to send the user a copy of the terms and conditions after he’s accepted them.
