Copilot Studio Checks User File Uploads
Microsoft Copilot Studio users can enable File Uploads and create a Topic that checks the built-in Activity.Attachments variable to determine whether a file was uploaded in the same interaction. The post explains enabling File uploads, adding a Condition to test Activity.Attachments is empty, and prompting users to attach a file or validating formats (.pdf, .docx). Practitioners can use this pattern to avoid empty queries and enforce file-format checks before analysis.
Key Points
- 1Implements Condition checking Activity.Attachments to detect file uploads within the user's initial message
- 2Prevents empty queries by prompting users to upload files, improving agent context and response relevance
- 3Enables developers to branch Topics, validate file formats (.pdf, .docx), and enforce upload policies
Scoring Rationale
Practical, directly actionable guidance for Copilot Studio users; limited novelty and narrow product scope reduces broader impact.
