Work with unrecognized files and check their extensions by analyzing the first bytes containing information on what format is used. The utility scans the data and suggests one or several possible extensions. It works with COM, HOME, BIN, DLL, VBX, etc.
Ever received an unknown file and didn't know how to open it? Ever had a file with 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, many filename extensions and tries to suggest applications for viewing.
