It's not always possible to see from a filename's extension what format is used. Sometimes the same extension is used for different formats or often a file simply has a wrong extension. WhatFormat is a file analyser that checks the first bytes of a file for signatures to try to determine it's format. It also knows many filename extensions and suggests applications for viewing.
