Save a Single Email Attachment to Disk

Demonstrates the Chilkat Email.SaveAttachedFile method, which saves the attachment at a given zero-based index to a directory. If the directory or any of its components do not exist, Chilkat creates them. This example adds an attachment and saves it.

Background: Where SaveAllAttachments writes every attachment at once, SaveAttachedFile saves just one by index — useful when you have inspected the attachments (by type, name, or size) and want to extract only a specific file. The attachment keeps its own filename; the same filename-safety considerations apply as when saving all of them.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

//  Demonstrates the SaveAttachedFile method, which saves the attachment at a given
//  zero-based index to a directory.  If the directory (or any of its components) does not
//  exist, Chilkat creates it.

var email = new CkEmail();
email.Subject = "Save one attachment";

email.AddStringAttachment("report.txt","Attachment content.");

//  Save the attachment at index 0 into the specified directory.
success = email.SaveAttachedFile(0,"qa_output/attachments");
if (success == false) {
    console.log(email.LastErrorText);
    return true;
}

console.log("Saved attachment 0.");

//  Note: The path "qa_output/..." is a relative local filesystem path,
//  relative to the current working directory of the running application.
