2720 Microsoft Powerpoint for Macintosh 2 Presentation Microsoft PowerPoint Presentation is a proprietary binary file format developed by Microsoft Corporation used to store presentation files created in the Microsoft PowerPoint presentation system. This record describes version 2 of .ppt file format for Macintosh, released in May 1998. Versions up to version 4 of Microsoft PowerPoint use .ppt as extension, however they are not compatible with each other. Microsoft made backwards compatibility an optional add-on after Office 2003 and appears to have removed it altogether in Office 2010. 299 Brigham Young University / Brigham Young University 24 May 2023 24 May 2023 application/vnd.ms-PowerPoint MIME com.microsoft.powerpoint.ppt Apple Uniform Type Identifier fmt/1866 PUID ppt File extension 2210 Microsoft Powerpoint for Macintosh v.2 Absolute from beginning of file, magic bytes: ''Þí.... 1 Absolute from BOF 0 0 0BADDEED00000002
