Getting Files from Users in Copilot Studio

Is there still no way for users to provide files in a chat? e.g. say you where creating a homework bot that asked students to submit their pdf essay

I know there is the outdated option of using something like https://github.com/microsoft/CopilotStudioSamples/tree/master/BuildYourOwnCanvasSamples/2.location-and-file-uploading to get the files, but it's dependent on an outdated version of Node and doesn't integrate well with custom sites.

Seems like an oversight on Microsofts part if the feature does not exit.

Hi UL-09100816-0,

As of now, Copilot still don’t natively support file uploads directly through bot conversations.

Anyhow there are some articles that states that this feature will be introduced soon in Copilot during next release.

Workaround as of now:

You can integrate Power Automate with your bot to handle file uploads. In this scenario, you can send the user a link (e.g., OneDrive, SharePoint) where they can upload files, and then Power Automate can track the uploaded files and feed the information back to the bot. The bot could guide the user to upload their file, and after the file is uploaded, Power Automate can trigger actions such as sending a confirmation or processing the file.

Hope This Helps !

Thanks.

Hi @UL-09100816-0,

Though you likely found a workaround to this question by now, in case you haven't, you can indeed upload files to custom agents in copilot studio via custom Topics now!

One caveat is that as of November 2025, Co-pilot studio does not support multiple file uploads automatically; only one file at a time.

However, you create a custom Topic, set up your trigger, and snag the first record of the System.Activity.Attachments table, which should be the file uploaded. Attached is a screenshot.

Create a new topic

Set up your desired trigger

Click "+"

Select "Set a variable value"

Name your variable then use the fx to write First(System.Activity.Attachments)

You can then send this variable to a custom action for further processing.

I hope this helps!
