> In this case, the content is located in eight slide*.xml files (where the asterisk is a sequential number) inside the slide folder within the ppt folder. These folders and files are completely different to those in the XLSX and DOCX files, but information relevant to displaying slides on screen is scattered throughout them. Again, there are no technical reasons for the differences in the XML schemas of the three files other than to make their internal structures more complex. This unnecessary complexity is also reflected in the XML files describing the contents of the presentation.

This is why I absolute hate Microsoft
