PPT（Microsoft PowerPoint 二进制演示文稿）
PPT 是 PowerPoint 97-2003 使用的旧版二进制演示文稿格式。它以专有的复合二进制文件存储幻灯片、图形和过渡效果。PPT 文件在旧归档中仍可见到，但已被 PPTX 取代。
MIME 类型
application/vnd.ms-powerpoint
类型
二进制
压缩
无损
优点
- + Compatible with PowerPoint 97-2003 installations
- + Supports embedded OLE objects and legacy VBA macros
- + Well-supported by conversion tools for migration to PPTX
缺点
- − Larger file sizes than PPTX
- − Proprietary binary format with limited third-party support
- − Does not support modern Office features like SmartArt or 3D models
何时使用 .PPT
仅在与 PowerPoint 2003 或更早版本用户共享时使用 PPT；转换为 PPTX 以获得现代兼容性和更小的文件。
技术细节
PPT 文件使用 OLE2 复合二进制格式，包含幻灯片、文本、形状和动画的专有记录类型。二进制结构使得直接编辑和解析比 PPTX 复杂得多。
历史
PPT 二进制格式为 PowerPoint 早期版本开发，在 PowerPoint 97 中成熟。在 Open XML 转型之前，它主导了演示文稿市场十余年。
