A Hex Editor is a specialized software tool that allows users to view and edit the raw binary data of files. It displays the data in hexadecimal format, which is a base-16 numbering system, making it easier to analyze and manipulate the underlying structure of files. This is particularly useful for programmers, data recovery specialists, and digital forensics experts who need to inspect or modify file contents directly. Hex editors can be used for various purposes, such as debugging software, modifying game files, or recovering lost data. They provide features like search functions, data comparison, and the ability to edit specific bytes. Popular examples of hex editors include HxD, Hex Fiend, and 010 Editor.
