Question details

The user wants to use a locally stored Word document as a reference file for Microsoft 365 Copilot, but standard methods like drag-and-drop or entering the local file path are failing.

Product: Microsoft Word / Copilot
Device & OS: not provided
Scenario: Attempting to generate content or query Copilot using a local Word file as the data source.
Observed behavior: Dragging the file into the Copilot prompt or typing the local file path does not work, preventing Copilot from accessing and utilizing the local document.

Before you start

Ensure you have an active Microsoft 365 subscription with the required Copilot entitlement and that you are signed into your OneDrive or SharePoint account.

Solution 1Recommended

Upload Document to OneDrive or SharePoint

Since Copilot cannot access local files via path or drag-and-drop, the file must be uploaded to Microsoft's cloud storage before it can be referenced.

Microsoft 365 Copilot operates via cloud services and does not have direct access to your local hard drive paths. To reference a document, it must be hosted securely in your connected Microsoft cloud storage.

Sign in to cloud storage

Open your web browser or file explorer and sign in to your Microsoft OneDrive or SharePoint account.

Upload the local file

Upload the local Word document you wish to use as a reference into your cloud drive.

Open the document in Word

Open the newly uploaded cloud document in the Word desktop app or Word for the Web.

Launch Copilot

Click the Copilot icon on the Home tab of the ribbon. You can now prompt Copilot to summarize, rewrite, or reference the content of this document successfully.

Subscription Requirement: The capability to reference documents is not inherently limited to Copilot Pro, but your Microsoft 365 subscription must include the required Copilot entitlement for your account type.

Frequently Asked Questions

Can I just drag and drop a local Word file into the Copilot prompt?

No, Copilot in Word currently does not support local drag-and-drop file attachments directly into the prompt box. The files must be hosted on OneDrive or SharePoint to be referenced.

Do I need Copilot Pro to use reference documents?

Referencing documents is not exclusively limited to Copilot Pro. However, you must have an active Microsoft 365 subscription that includes the appropriate Copilot entitlement for your specific account tier.

Why does entering the file path not work in Copilot?

Copilot processes prompts via Microsoft's secure cloud infrastructure. For security and architectural reasons, it cannot read files directly from local hard drive paths (e.g., C:\Documents).
