Is there a simple way to retrieve a DOS path like C:\dir1\file1 using FltMgr?

I couldn’t find a function in the filter manager to get a DOS drive name. If
I call RtlVolumeDeviceToDosName or IoVolumeDeviceToDosName, I need get the
device object of a volume. Although it seems not a problem to get the device
object based a volume name, the approach involves to check the platform
version in order to call the functions properly. If there is a direct and
simple way to get it, please provide the information.

Thanks in advance,

Use FltGetDiskDeviceObject() to get the Volume Device Object, then
RtlVolumeDeviceToDosName() to get the DOS name.
