Binary files are like the secret codes of the computer world. They contain data that's only readable by machines, making them super useful for storing and transferring info. But, to actually see what's inside, you need to decode them, and that's where things get interesting.
On Windows, you can use a variety of tools to open and view binary files. One popular option is Notepad++, a free text editor that can handle all sorts of file types, including binary ones. You can also use the built-in Windows Debugger or Hex Editor for a more in-depth look.
