Attach a File to a Multipart MIME Entity

Demonstrates the Chilkat Mime.AppendPartFromFile method, which reads a local file, creates an attachment part, and appends it. The only argument is the file path; the content headers are chosen from the filename extension.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is the one-call way to add an attachment: Chilkat reads the file, infers its Content-Type from the extension, base64-encodes binary content, and appends it as a child part — typically inside a multipart/mixed. It is the building block behind adding attachments to an email, saving you from constructing the part and setting its headers by hand.
