Since voil uses its own file extension (.voil) you can easily disable copilot for voil windows.

Also voil asks you to confirm destructive actions. And even if you do, by default voil moves deleted files to a trash location and has undo functionality so you can easily undo your mistakes.

In this day and age, this could very well be an up and coming startup. "Hey <LLM>, find all files on my computer that might be a virus and delete them."
