It is used to store optical disc images in a reduced-size form for software distribution, backups, and mounting in virtual drives. The format is generally safe, though, like other disk images, it should be opened only from trusted sources because it can contain executable content or malicious files.","mime":[],"risk_level":"Safe","signatures":[{"hex":"49 73 5A 21","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":[],"usage":{"python":"def is_isz(file_path: str) -> bool:\n    \"\"\"Check if file is a valid ISZ by magic bytes.\"\"\"\n    signature = bytes([0x49, 0x73, 0x5A, 0x21])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isISZ(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x49, 0x73, 0x5A, 0x21]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsISZ(data []byte) bool {\n    signature := []byte{0x49, 0x73, 0x5A, 0x21}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
