You need to use FltParseFileNameInformation -
https://msdn.microsoft.com/en-us/library/windows/hardware/ff543417(v=vs.85).aspx

https://msdn.microsoft.com/en-us/library/windows/hardware/ff543032(v=vs.85).aspx

To parse the contents of the FLT_FILE_NAME_INFORMATION structure returned
by FltGetFileNameInformation, call FltParseFileNameInformation.
