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."
