Description As part of Microsoft's 2007 suite another open XML document type was introduced. This time in the PowerPoint sphere, PPTX is a Presentation format that stores slides used for slide shows or presentations; like a normal PPT format it may include text, images, and other media; however PPTX is based on the Open XML format and uses ZIP compression for smaller file sizes
Actions
Technical Details A PPTX file is quite unique. The specifications for PPTX are in the ECMA-376 standard for Office Open XML. You can make a PPTX file by zipping up a directory, but the material in the directory has to match an OPC structure, including subfolders that have the content in XML format. Any application that supports XML can access and work with data in the new file format. Just like the DOCX file format, PPTX improves file and data management and data recovery.

Description DOCX was introduced with Microsoft Word 2007, it's based on open XML and uses ZIP compression for smaller file sizes. The benefit of having open XML is that it is able to be read by applications, platforms and Internet Platforms. However to open it using any Microsoft Word that predated 2007 would require DOCX to be converted into a normal doc format.
Actions
Technical Details DOCX improves file and data management and data recovery. DOCX extends what is possible with the binary files of earlier versions. Any application that supports XML can access and work with data in the new file format. The application does not need to be a Microsoft product it can be any application. Users can also use standard transformations to extract or repurpose the data. In addition, security concerns are drastically reduced because the information is stored in XML, which is essentially plain text. Thus, the data can pass through corporate firewalls without hindrance.
