Get the Filename of an Attached Message

See more Email Object Examples

Demonstrates the Chilkat Email.GetAttachedMessageFilename method, which returns the filename of the Nth attached (embedded) email. The filename is the filename attribute of the attached message's Content-Disposition header, and the index is zero-based. This example attaches an email and reads the attached message's filename.

Background: When an email forwards another message as an attachment, the nested message is a message/rfc822 part — a complete email tucked inside the carrier. Mail clients often give that part a filename (like forwarded.eml) via its Content-Disposition header so it can be saved to disk. This method reads that filename directly. Attached messages are counted separately from ordinary attachments (see NumAttachedMessages).
