All editable material comes in two formats:
doc/ppt/xls format used in Office 2003
docx/pptx/xlsx format used in Office 2007 and future versions
When you order training materials from us, the collection of files that you receive contain both versions in separate folders. The course materials are designed using Office 365. The latest version released is Office 2016. The files are backward and forward compatible with Office 2007, 2010, 2013 and 2016. They are converted to Office 2003 for those who prefer to use this version instead. Documents are in MS Word, slides are in MS PowerPoint and with some courses MS Excel files are frovided as extra content or handouts.
If you are interested in editing our training materials, you can use any of the available versions such as Office 2003, 2007, 2010, 2013 or 2016. If you are using Office 2010 or later versions, you can take advantage of all the editing functionality that the software provides to modify the content. Using Office 2010 or later is not a requirement and you can use other previous versions to edit the content as well.
Microsoft released a software update for those who use Office 2003, so they can also edit image compositions made using "Smart Art" in Office 2003 without the need for later versions. If you are using Office 2003, you are advised to use a free upgrade from Microsoft to view MS 2007 files with MS 2003  which allows you to edit the content more efficiently.
