File system info - how to query it?

Question

Is there a way to access file system info via some type of Windows API? If not what other methods are available to a user mode developer?

Answer 1

Not very clean, but you can use DeviceIoControl() Open volume as a file, pass resulting handle to DeviceIoControl() together with control code. Check MSDN for control codes, there is something like "read journal record".
