Which tool is used to manipulate the binary data that makes up a computer file?

• A. Decode Editor
• B. Proxy Server
• C. Hex Editor
• D. Shadowsocks

Answer: (C)

Editing the raw bytes that comprise a file is done with a hex editor. A hex editor displays the file as hexadecimal byte values (often with an accompanying ASCII view), allowing you to see and modify every single byte. This byte‑level access is essential for patching headers, fixing corruption, or altering embedded data that isn’t meaningful as plain text. The other tools mentioned don’t operate at that byte level: proxies route or transform network traffic, and a general decoding tool isn’t used for direct binary manipulation, so they can’t edit a file’s binary contents the way a hex editor can. Therefore, a hex editor is the tool designed for manipulating the binary data of a file.
