XF 1.5 How to add copyright files to attachments

[Dadparvar]

Hi,

Is it possible:

• when users attach files (to be downloaded. non-image files), the system automatically add some files that we want and then zip them?
• or, just make the attachment zip with some comments on zip file?

Is this possible? Is there any ad-on for this?

Regards,
Hamed

This would require custom development.
