Contact Form 7 supports local file attachment. You can put local file paths in the File Attachments field and those files will be attached to the email as well as uploaded files.
Put a file path per line. When the path is not an absolute path, it will be treated as a relative path to the wp-content directory.
For security reasons, specifying files outside of the wp-content directory for email attachments is not allowed, so place the files in the wp-content or its subdirectory.
