Bulk Delete of Files uploaded for generative answers

Posted on by ryjan

Hi all,

I am using the upload files feature for creating generative answers. Anyway, I am uploading about 100 files, which are changing sometimes. It is possible to upload all files at once, but I have not found any possibility to delete all or selected files that are not relevant anymore. It is quite odd to delete each file https://learn.microsoft.com/en-us/microsoft-copilot-studio/nlu-documents

I have searched in Dataverse tables but I have not found the storage location - my idea was to create Bulk Delete Job.

Any hints on how to find and delete the files in bulk?

Hi @ryjan
Only solution I can see is to delete the files from the Dataverse table (documents are in the table chatbot subcomponent, type Bot File Attachment)

Hi @remidyon, thanks for suggestion. Unfortunately the table is read-only, even if I am System Administrator in that environment

When trying to delete them from the default solution, I get an error message:

Hi @ryjan
I finally found a workaround using Power Automate: you can list the rows that are type "Bot File Attachement" and then perform an "unbound action" with the "DeleteFile" action.

Here is a test where I go list a particular file I want to delete from my Copilot:

Once I have listed the files, I can access them with their fileID and unbound them from the table (it will keep the record but remove the actual file data - which will make the file disappear from the UI in Copilot Studio as well)
In the meantime I have opened a feature request for our product group to add the ability to delete in bulk from the UI.

Hope this help.
Remi

@remidyon Your solution does not work well in large organizations where the table "Chatbot subcomponents" have stuff from multiple chatbots and you need to delete all .txt files added to a custom copilot made with copilot studio. Microsoft should make the table in "knowledge" in copilot studio "multiple select" so that we can delete more than 1 file at a time.

I solved this with a stupid script in AutoHotkey where "680, 395" is the position of the button to open the "kebab menu" for each file in "knowledge" and the keypresses is for deleting and closing the "are you sure" -dialog.
I removed like 100 files in a few minutes.

WARNING: When all "files" have been deleted, it will start deleting SharePoint etc. since the filter for "Files" is removed when there are no files. So perhaps just use this script if you just want to delete everything.

Click 680, 395
