What is a PPTX file?
Files with the .PPTX extension contain presentation files saved in an open XML format, which means that the data is stored separately, as files in a ZIP pack, with their description contained in the XML file, also located in the pack. When the file is unpacked, one can find text files, images, formatting, animations, drawn objects, as well as information about the individual presentation slides. This is a very easy alternative to binary PPT files.
Files of this type are created by presentation-making software, such as Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress, and used for creating business-oriented, academic, and sales presentations.

Advantages of PPTX compared to PPT
PPTX format is the successor to PPT format and offers some additional features. PPTX has the advantage over it predecessor that it makes using, managing and recovering file data much easier. PPT file stores all presentation data in a single binary file, whereas PPTX format, which is based on Open XML standard, splits the data into smaller groups of files and stores them in a ZIP archive. This solution allows for embedding audio and video files, images, macros, and other multimedia as separate files for added mobility and flexibility. PPTX files aren’t entirely based on XML format – some sections of the files are in binary. ZIP compression allows for smaller file sizes and easier file distribution. Modular structure of PPTX files offers addtional protection from data corruption, and the built-in privacy protection features make cleaning files metadata much simpler.
How to open PPTX files
If you cannot open the PPTX file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports PPTX among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the PPTX file can be found in the table. Now just download and install the appropriate application.
Possible problems with the PPTX format files
The inability to open and operate the PPTX file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft PowerPoint 2007/2010 Open XML Presentation Format file. Below is a list of possible problems.
- Corruption of a PPTX file which is being opened
- Incorrect links to the PPTX file in registry entries.
- Accidental deletion of the description of the PPTX from the Windows registry
- Incomplete installation of an application that supports the PPTX format
- The PPTX file which is being opened is infected with an undesirable malware.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.PPTX) you have two ways to do it. The first and the easiest one is to right-click on the selected PPTX file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the PPTX file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. PPTX) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
