# Safer attachments, previewed in place

Attachments just got safer and easier. When you open a conversation, Doota now
**checks each file** against known-dangerous patterns — right on your device,
nothing uploaded — and shows a small badge: **Checked**, **Threat found**, or
**Couldn't check**. Risky or unverifiable files ask you to confirm before they
open.

Most files now **open in place**, in a walled-off preview that can't touch your
account or the rest of the page: images, PDFs, text, **audio and video**, and a
richer view for **Office documents, spreadsheets, slideshows, markdown, and
zips**. Step through a message's files with arrow keys, or grab the one you want
with the download button — no more downloading blind just to take a look.

See [Attachments](/guide/attachments) for the details.
