bin
What is a .bin file?
application/octet-stream
A .bin file is a generic binary blob with no specific format — raw bytes whose meaning depends entirely on the producing application (firmware images, memory dumps, serialized payloads). The extension signals only 'not text.'
How to use a .bin file
Use an example .bin file to test binary/hex viewers, file-type sniffing, octet-stream handling, and download pipelines that must not corrupt arbitrary bytes.
