Have you encountered a problem with a PPTX file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a PPTX file here. In the further part of this page we have added a list of programs that should open your PPTX file. It is enough you choose a proper application for your operating system, download and install it.


The file extension PPTX is the latest version of the Microsoft Powerpoint file format ppt. The PPTX format will be supported from the 2007 version of the worldwide presentation program. The file extension PPTX simply means Powerpoint Presentation Xml, ie a PowerPoint presentation in XML format.

A PPTX file, like the old ppt files, can contain not only formatted text, lists, pictures, videos but also music and Excel spreadsheets, which are divided into boards or slides. In addition, many elements can be animated or fade in and out, as well as with different effects. PPTX files can not contain macros, files with macros automatically get the extension pptm. The files are editable and will not start automatically.

PPTX is an XML based file format (Office Open XML) that is unreadable with older versions of PowerPoint. For the Office versions 2000, 2003 and XP, however, this functionality can be retrofitted with the help of the Microsoft Office Compatibility Pack, whereby the result of an imported PPTX file does not always have to be 100% identical to the original.

Office Open XML is an open standard developed by Microsoft for office applications, which is intended to ensure the file exchange between different office suites.

A PPTX file consists of several XML files, which are automatically combined with the ZIP algorithm as an archive when saving. This saves space compared to the old format. Other benefits include better data integrity and easier data recovery in the event of data loss.

How to open a PPTX file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PPTX file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a PPTX file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support PPTX files. At this point we are looking for disk space where the application was installed in and we can link it with a PPTX file. Since then, our operating system will use the selected program to support all PPTX files.

Other issues

Despite the described problem with PPTX there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the PPTX file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the PPTX file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
