# Can I comment on a specific line, page or moment in a Delta Drive file?

Yes. In the browser viewer a comment can point at a line or lines, a page, an area or point on a page or slide, a moment in a video, spreadsheet cells, a paragraph or highlighted text. If that text later disappears, the comment says so.

- Reply, react, and edit your own comments; **Resolve** threads when done.
- Turn a comment into a **Task** or a **Checklist** with an assignee and a due date, and filter by Open, Resolved, Mine, Mentions or overdue tasks.
- **@mention** someone who can already open the file — they're emailed; a mention never reaches anyone who can't open it.
- **Suggest a change**, copy a link to a comment, and set the file's review status: **Not reviewed**, **In review**, **Approved** or **Changes requested**.

Owners also get **Viewed by…**, **Lock comments** and exports. Visitors to a public link see no comments unless you turn on **Show resolved comments on public links**.
