MS PowerPoint is one of the best presentation programs designed by Microsoft. It is widely used to create presentations in the form of slide shows. The presentations are excessively used nowadays in every businesses and organizations. They are commonly used for business, training and educational purposes. In MS PowerPoint program we can easily create an awesome and attractive presentation by using text, graphics and animations. We can also make charts, tables, and macros and as well as we can add images, audio, video and other multimedia files in our presentation files. PPTX is a file type which is primarily associated with MS PowerPoint 2007 and it can be easily opened by any XML supportable program.  

[MS PowerPoint really offers a good amount of features but there is a bitter truth about those PowerPoint files that they can be easily corrupted at any point of time.]   

To make a presentation in MS PowerPoint it really takes a great piece of hard work and much time. But it can be corrupted in just seconds and all our hard work will become useless after corruption. A corrupt .pptx file can't be viewed or opened anyhow. Suppose you have no idea about corruption and as usual you open any particular file but instead of opening you receive an error message indicating sometime wrong with your file. At that point of time you come to know about the file corruption.

At the time of corruption a file becomes inaccessible and content inside it becomes invalid or unreadable. Just have a look on these error messages which are frequently encountered on front of our screen:

• "PowerPoint was unable to display some of the text, images, or objects on slides in the file."
• "File is corrupted or damaged."
• "There was an error accessing xxxx".
• "This is not a PowerPoint Presentation."
• "Part of the file is missing."

There are lots of factors which can badly affect our Pptx files and make them inaccessible such as virus infections, unfinished system shut down or saving process, sudden termination of MS PowerPoint, crashed in system hard drive, network problem while downloading file and many more.

In this crucial situation of Pptx corruption we can do three things to fix it.

1. If the file corruption is normal (not heavy) then we can import the file objects of that corrupt file into a new fresh file. And after creating a backup for that new Pptx file we can use that.
2. If our Pptx files are heavily corrupted then we can take help of a backup file which is created for those Pptx files and restore them from the backup file.
3. In the case when Pptx files are heavily corrupted or damaged and we don't have any backup to restore them then at that time we can use a file recovery application for MS PowerPoint.

When the time comes to choose a software program we must choose an effective solution very cautiously. MS PowerPoint Pptx Recovery is generally said the best file recovery tool in this case. We can use it when there is a heavy and unbearable corruption in our Pptx files. It perfectly fixes corrupt .pptx files which are not opening and makes them able to be opened. All our file objects which we have added into our presentations can be easily recovered by this tool. And to get 100% surety about this software program we can use its demo version first before actually buying it.
