# File Attachments

> Attach a document or source file when a question asks you to upload your work.

Use **Attachment** inside a [written response](/students/assessments/questions/written-responses) when a question asks for a document or source file. You can add an explanation in the same response editor.

## Answer With a File

<Tip>
  Upload the file itself. A link to a document on another website is not graded as an attachment.
</Tip>

If the response area only offers image uploads, follow the [image-response guide](/students/assessments/questions/image-responses). For a recording with playback controls, use [Audio](/general/tools/audio) in the written-response editor.
