Overview

PPTX is a Microsoft PowerPoint 2007, Open XML Presentation file which is similar to its predecessor that is PPT. It is an open-source file under XML that is why it can be opened easily in other types of presentation programs. It can have a number of slides which can be used to present the ideas or to deliver lectures at all the platforms. For instance- In business meetings, academic classrooms and other market applications. As earlier versions of Microsoft PowerPoint do not support open version that is why it was launched in 2007 with open standards to cope up with the competition in the market. The slides in this can store images, content, graphs, tables, audio, video, graphics and animations; etc. Other software that supports it include OpenOffice Impress and Apple Keynote.

Technical description

The data that is stored in PPTX is compressed with ZIP compression technique and is reserved in separate files and folders. ECMA-376 standard is used by these files for Office Open XML. The directory is zipped together to create this file and the information in it matches the OPC (Open Platform Communications) structure. A user if wants to make his presentation absolutely attractive to the audience can add custom settings to the text and other content on the slides. Animation effects can be added to the entry, appearance and exit of the text.

Overview

Originally, Robert Gaskins and Dennis Austin of Forethought, Inc. created this file format to make presentations using PowerPoint. Later on, Microsoft acquired this and now it is one of the components of Microsoft Office suite. These PPT presentations include a number of slides, where the content has images, texts with varied font style and size, hyperlinks, audio, video, charts, tables and graphs; etc. We can also apply different themes and animation effects to the text as well as to the images. This in result, can make the presentation interesting instead of dull and boring. One can bring variations to the text, that is how it enters, appears and leaves the screen. Earlier it was meant only for businesses, but now, it is widely used at every platform to showcase the knowledge or ideas effectively.

Technical description

PPT consists of a number of slides which are just like different pages of a notebook. There are in-built templates which can be used to add text with titles or subtitles and images at various places. For example – there is one template for comparing the things. Therefore, two things can be compared by just adding the text. There is no need to add extra centre line to make comparison. Besides this, there comes one master slide. This slide is used to provide overall design to the presentation and it indicates how other slides should appear and work. One can also take the print to review the document. When Microsoft Office 2007 came into existence, PPTX replaced it as this new extension was based on open XML format.
