Generate a Unique Filename for an Email

Demonstrates the Chilkat Email.GenerateFilename method, which generates a unique filename for the email. The returned filename is different each time the method is called. This example generates one and prints it.

Background: When saving many messages to a folder — for example exporting a mailbox to .eml files — you need a distinct name for each so they do not overwrite one another. GenerateFilename produces a fresh, collision-resistant name on demand, sparing you from inventing your own scheme (timestamps, counters, GUIDs) just to keep files from clashing.
