Application/octet-stream

Application/octet-stream is a standard way computers specify that a file contains binary data, meaning it’s raw information that’s not formatted for a specific type like text, images, or videos. It acts as a generic label indicating the file is arbitrary data, often used for downloads or transfers when the exact file type isn't identified. Essentially, it’s a neutral category signaling the system to treat the file as unrecognized or as a blank slate, requiring appropriate software to interpret or open its contents.
