Automatic deletion of non-Google file versions
We may automatically delete older versions of non-Google files to help free up your storage. After 30 days, anything over 100 versions (per document) will be automatically deleted. If you’ve marked a version as "Keep forever", we won’t delete it but you won’t be able to keep more than 200 versions (per document).
