Unzip an Email's Zip Attachments

See more Email Object Examples

Demonstrates the Chilkat Email.UnzipAttachments method, which unzips and replaces any Zip file attachments with their expanded contents. For example, if an email contains a single Zip holding three files, that Zip attachment is replaced by the three files as individual attachments. This example loads an email and expands its Zip attachments.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
