When you open the ZIP package for an Excel or PowerPoint 2007 file, you'll see several things that look identical to the Word 2007 ZIP package shown on preceding screens. However, once you open the xl or ppt folders (the main document folder names for Excel 2007 and PowerPoint 2007 files, respectively), you will find a few differences.
- In place of the document.xml part, you see a workbook.xml part for Excel 2007 files and a presentation.xml part for PowerPoint 2007 files, along with other program-specific XML parts (such as styles.xml for Excel and tableStyles.xml for PowerPoint). Just as with Word 2007 documents, additional XML parts may exist for additional types of content.
- PowerPoint 2007 files contain additional subfolders for slides, slideLayouts, and slideMasters, in which you find separate XML parts for each slide, layout, and master (respectively) contained in the presentation.
- Excel 2007 files contain additional subfolders for worksheets and for print settings. The worksheets folder contains a separate XML part for each worksheet in the workbook.
