Why do attachments matter in a document review?

In a technical review, attachments are the evidence: the wiring diagram that shows the pinout is wrong, the test log behind a changed spec, the screenshot of the setting the manual describes. When that evidence is buried in reply threads, or sent separately by email, the writer asks for it again and the next reviewer never sees it. Keep each file on the reply it supports, so it stays with the comment and with this version of the document, and look them all up in one place when you need them.

Transcript

Reviewers attach diagrams, specs and screenshots to their replies. Here’s how to find all of them at once.

Open the left panel and click the paperclip tab, Attachments. Every file attached to a reply is listed by page, with who added it. Click a file to download it.

Attach a new file to a reply and it shows up here right away. No attachments yet? The panel tells you.

The step-by-step guide is in the description.

Where do I find the files reviewers attached to a PDF review?

Open the PDF in the review view, click the Left Panel icon in the top-left toolbar, then the paperclip (Attachments) tab. Every file attached to a reply on a comment is listed there, grouped by page, with the file name, file type and who added it.

How do I attach a file to a comment on a PDF?

Open a comment thread, click into the Reply field, click the attachment icon and upload the file, then submit the reply. The file stays on that comment thread and appears in the Attachments panel.

Which files can I attach, and how big can they be?

Each attachment must be 5 MB or smaller. Allowed types are pdf, doc, docx, xls, xlsx, ppt, pptx, jpg, jpeg, png, txt and csv.

Why is a file missing from the Attachments panel?

The panel lists files attached to replies. Files attached to the first comment of a thread are not listed yet, so attach evidence as a reply to the comment it supports.
