What to do about it
PromptDust flags these stores and leaves them in place; cleanup is your call. If a store holds a live secret, rotate the secret first, since deleting the file won’t un-leak a key that already sat in plain text.
For ongoing work, keep sensitive material out of sessions where you can, and prune old transcripts and caches now and then.
This describes where Microsoft Copilot stores data. Metadata only, never your content. Confidence: likely. Spot a mistake? Tell us.

One pass finds every store, for this tool and the other 51.
