# Attach a file as a comment

You can add a sound or file attachment as a comment by using the Attach A File As A Comment tool or the Record Audio Comment tool in the Commenting toolbar. These attachments are tracked with other comments in a review workflow (unlike file attachments, which you create using the Attach A File tool in the File toolbar). PDF comment attachments open in a new window. To view non-PDF file attachments, the user must have an application installed that can view or edit the attached file.
