Hi Dain, The ORC spec requires that a file start with "ORC".
>From https://orc.apache.org/docs/file-tail.html "The file is broken in to three parts- Header, Body, and Tail. The Header consists of the bytes “ORC’’ to support tools that want to scan the front of the file to determine the type of the file."
