Slides usually in PowerPoint format.
PDF versions of some of files are placed
into subdirectories "PDF_versions"
Note:
I tried to also convert to HTML format,
but didn't find a convenient way of doing this.
For example, the aspose online converter is reasonably good,
but unfortunately it doesn't preserve the font type:
