我上传了一个word文件到Copilot Studio，为什么文件丢失了，我想删除文件，怎么做

Categories:

All files uploaded to Copilot Studio using the Generative AI tab are stored in Dataverse. You may have uploaded an unsupported file type, or reached capacity in Dataverse, which might explain your experience, but honestly I have not seen this. Please do raise a support ticket if files are disappearing as you explained.

This article explains how to manage, and to delete, uploaded files - as well as which file types are supported:
Use uploaded documents as a generative answers data source (preview) - Microsoft Copilot Studio | Microsoft Learn
or use this localized link: https://learn.microsoft.com/microsoft-copilot-studio/nlu-documents.

Note: If you need more files and have run out of upload options, remember you can also reference a SharePoint site where many documents are stored. See here: https://learn.microsoft.com/microsoft-copilot-studio/nlu-generative-answers-sharepoint-onedrive
