I know file system is locate on top in driver stack.
Can I know which format(ef. NTFS or Fat32 etc) file system is on the top?

Is it using IoGetTopLevelIrp function?
If it does, how can I know this file system is NTFS or Fat32 format?

Just I want to file system driver symbolic link name.

Thanks in advence.

You can try IoGetBaseFileSystemDeviceObject or IoGetDeviceAttachmentBaseRef

Send FileFsAttributeInformation query to the filesystem, this will return its name.
