Thank you for the suggestion. This feature was considered many years ago, but was put on hold again due to the complexity. The only way to obtain the type of details we would require is the development of a driver, which is a significant undertaking.
While it's definitely something we're interested in, file monitoring is only one of many EventSentry features. And the benefit of native driver-based monitoring, while certainly useful, would be somewhat limited.
We will definitely take your input into consideration.
