How to extract and save attachments

You can save/export attachments from Email documents, Outlook data files, Archives and PDF documents with only a few lines of code using GroupDocs.Viewer for Java API.

Follow these steps to get and save (export) attachments:

Instantiate Viewer object for the file that contains attachment(s);
Call getAttachments() method which will return document attachments collection;
Iterate through attachments collection and save attachment by calling saveAttachment(…) method.

Following example demonstrates on how to get and save attachments from MSG files.

    String outputPath = "C:\\output";
    try (Viewer viewer = new Viewer("with_attachments.msg")) {
        List<Attachment> attachments = viewer.getAttachments();
        for (Attachment attachment : attachments) {
            String filePath = Path.combine(outputPath, attachment.getFileName());
            viewer.saveAttachment(attachment.getFileName(), new FileOutputStream(filePath));
        }
    }

NOTE: provided code example is actual for all document types that support attachments - Email documents, Outlook data files, Archives and PDF documents.
