Save All MIME Attachments to Files

Demonstrates the Chilkat Mime.PartsToFiles method, which recursively traverses the MIME tree and saves each part having a nonempty filename parameter to a directory. The first argument is the destination directory and the second is a StringTable that receives the saved filenames.

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 extracts every named attachment from a message in one call, walking the whole tree so it finds attachments nested inside multipart containers. It saves only parts that declare a filename — inline body parts without one are skipped — and reports what it wrote via the StringTable, which is handy for logging or follow-up processing. The destination directory must already exist.
