It is used to store slideshow content, including slides, media, and supporting resources, for sharing and distribution in a packaged form. The format is legacy and rarely used in modern workflows, but it is generally considered safe; as with any presentation file, users should open untrusted files with current antivirus and Office software.","mime":["application/vnd.ms-powerpoint"],"risk_level":"Safe","signatures":[{"hex":"D0 CF 11 E0 A1 B1 1A E1","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"4D 53 43 46","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":["ppt","pot","ppa","pps"],"usage":{"python":"def is_ppz(file_path: str) -> bool:\n    \"\"\"Check if file is a valid PPZ by magic bytes.\"\"\"\n    signature = bytes([0xD0, 0xCF, 0x11, 0xE0, 0xA1, 0xB1, 0x1A, 0xE1])\n    with open(file_path, \"rb\") as f:\n        return f.read(8) == signature","node":"function isPPZ(buffer: Buffer): boolean {\n  const signature = Buffer.from([0xD0, 0xCF, 0x11, 0xE0, 0xA1, 0xB1, 0x1A, 0xE1]);\n  return buffer.subarray(0, 8).equals(signature);\n}","go":"func IsPPZ(data []byte) bool {\n    signature := []byte{0xD0, 0xCF, 0x11, 0xE0, 0xA1, 0xB1, 0x1A, 0xE1}\n    if len(data) < 8 {\n        return false\n    }\n    return bytes.Equal(data[:8], signature)\n}"},"category":"Office"}}
