# Quickstart: View attachments

A PDF may have other PDFs attached to it, either as single files or a PDF package. When you open a PDF containing attachments, the Attachment panel opens automatically.

Double-click the desired PDF. The attachment opens in a new window.

If the attachment is a PDF package, the first PDF in the package opens along with a list of all PDFs in the package. Click a PDF to view it.
