What software do you use when you need to create a high-quality presentation as quickly as possible? You can ask a million people, 99% of them won't think twice and tell you: PowerPoint. Others might think of Open Office (cheapest solution), Corel Draw (the most advanced solution) and Keynote (because it's from Apple!!!). But your interest is not in the opinion of the majority. Microsoft rules this market and we are all loyal and grateful liege lords. After all, where would we be without Microsoft Office? Long live our bright future: the dark ages.
PowerPoint is an intuitive program that allows you to create projects of any complexity, from school reports to professional presentations. If you use the program properly, it is a simple yet very powerful tool with many features. Also, it's pretty reliable. Unfortunately, no one is safe from data loss. A presentation file can be corrupted for various reasons and you will whine and gnash your teeth because you didn't make a backup copy.

But don't despair: Microsoft has equipped PowerPoint with ways to recover corrupted data. And if you want to make the process more successful and less painful, my advice is: don't ignore the modern versions of the program. In Office 98-2003, which still has many followers, presentations are saved as *.ppt. Comrades, let's get rid of this backwardness! We've been in the 21st century for almost two decades: finally update to the latest software! And it really makes a difference: corrupted *. pptx-Files supported by Microsoft Office 2007 and later are much more recoverable than their older relatives.
Recover what you lost
Good, so something went wrong with your file. First make sure there is no problem with the device where the presentation is stored. Working with USB sticks or an external hard drive is generally not a good idea, especially on a computer you're unfamiliar with: who knows if there's anything wrong with the power supply or the USB controller? The chances of something going wrong are much higher when you use external storage. Run a disk check: for example, using the traditional Windows utility. If there are errors, copy the presentation from the damaged device to your main drive and try opening it from there. The problem may go away.

If the problem is not the storage medium but the * .ppt/.pptx file itself, you should use PowerPoint 's built-in recovery tools .
A modern version of the program recognizes a "damaged" document as soon as it is opened and, if the damage is not too great, it immediately proposes a solution. Double-click the file, wait for the program to load and the dialog box that appears, then click Recover . Did it work? Good if it worked! Resave your presentation and… take a deep breath.

However, many times you open a file and this dialog box does not appear. In that case, you need to go to PowerPoint – File – Open – then, in the window that appears, select the damaged file and click next to the Open button – select Open and recover from the list.

Not good? Microsoft technical support suggests some other solutions like copying the slides from the corrupted file to a new one. To do this, create an empty presentation - click Create Slide - Reuse Slide - in the column that appears on the right, click Browse - Browse File and select the corrupted file. Now the slides from the corrupted presentation should be copied to a new one.
The second option is to try opening the broken file as a template. The sequence of steps is similar to the last one: Open an empty presentation - in the Design tab, click next to Design - Find Design - and try to import the damaged presentation into PowerPoint in the form of a template.
Now you can change the file extension of your corrupted file from .ppt to .rtf and try to find some joy with Word. You might lose some data in the process, but it's probably better than nothing.
NOTHING WORKED! WHAT CAN WE DO?
If all your attempts so far have been unsuccessful, then you should contact special applications and services. Of course, you could have asked experts for help right from the start: this is the easiest and safest solution. But unfortunately this is not free. Information is the most valuable resource of all these days, so if you have to spend five to ten euros to save an important project, it shouldn't be too bad.

One of the most advanced .ppt / .ppt file recovery algorithms. pptx files is the one developed by File Master . You can recover files directly on website https://onlinefilerepair.com/powerpoint-repair-online.html via web interface (cost: $5 per file). These three steps will lead you to success: click the big orange button Upload and fix file on the page , select the corrupted file on your computer, enter your email address , pass oneCaptcha (this is the hardest part), wait - watch the preview, pay $5 and download the results . Finished.

This service informs the user in advance how many pages and objects he can restore, so you don't waste money on nothing. And when the internal architecture of the file is completely destroyed, which is common with .ppt files created with old versions of PowerPoint 98-2003 (you backward people!), the intelligent program recognizes files (images, videos, audio, electronic Tables) that were embedded in the presentation and saves them in a separate folder . So it shouldn't be too difficult to create a new presentation using the recovered files.
But if you need a full desktop solution for Windows, which is especially important if you have multiple corrupted files, I recommend Recovery Toolbox 's tool . A license for Recovery Toolbox for PowerPoint ( https://powerpoint.recoverytoolbox.com/ ) costs $27, but then you can recover unlimited files and your data is guaranteed to be kept confidential.
This powerful program has a simple interface: even your grandparents could use it. Seriously, don't worry. You don't need a special introduction for it!
There are no important details and no complicated settings : just open Recovery Toolbox for PowerPoint - select your damaged presentation - wait - and save the results. There are no traps.
