Class Sniff

java.lang.Object

ai.redouble.demo.extract.Sniff

public final class Sniff
extends Object

What a file is by its first bytes, which no extension can lie about. The formats the tiers know are signed: PNG, JPEG, GIF, WEBP, PDF, the zip that every Office document is, and the OLE2 container of the old ones. A file with none of these signatures is text or an unsigned binary, which is the classifier's question.
