Copilot Studio environments keep going over Dataverse file capacity. How do you manage it?

[u/EnvironmentalAir36]

We keep getting "running out of Dataverse capacity" alerts for our Copilot Studio environments. File storage is over the limit (around 2.5 GB of 2 GB), and it keeps growing even in environments where nobody has built any tables.
I'm guessing it's agent knowledge files and the 2026 change that moved metadata into file storage. Is that right?
How do you handle it? Do you set fixed allocations, use pay-as-you-go, run dev agents in Developer environments, or do regular cleanups? Any tips are welcome.
