Generally, a .bin file is a that contains data in a machine-readable format, rather than human-readable text. What is b7ef81a9.bin ? (Common Scenarios)
Before diving into this specific code, it's important to understand what a .bin file is. The ".bin" extension is short for "binary" and is used to denote a file that contains raw binary data. Unlike a text file which stores characters you can read, a .bin file contains data meant to be read and interpreted directly by a computer's processor. As a result, they can represent many different things, such as:
