Recovering a corrupted PowerPoint (PPT) file can be a critical task, especially if it contains valuable data or an important presentation. There are various methods to attempt recovery, both online and offline.
1. Understanding File Corruption
File corruption can occur due to various reasons such as unexpected shutdowns, software crashes, virus attacks, or hardware failures. When a PPT file gets corrupted, it might not open at all, or it might open with some missing or unreadable content.
2. Initial Steps to Try
Before using advanced tools, you can try some basic steps to see if the issue can be resolved:
a. Restart Your Computer
Sometimes, simply restarting your computer can resolve minor issues with software and files.
b. Try Opening the File in Safe Mode
Open PowerPoint in Safe Mode to see if the file opens. To do this, hold the Ctrl key while clicking on the PowerPoint icon to start the application in Safe Mode.
c. Copy and Rename the File
Create a copy of the corrupted PPT file and give it a new name. This can sometimes bypass the corruption.
3. Using PowerPoint’s Built-in Repair Features
PowerPoint has some built-in features that can help repair corrupted files:
a. Open and Repair

PowerPoint files are essentially zip archives. You can try to extract the contents manually:

Change the file extension from .pptx to .zip.
Extract the zip file using any archive tool (e.g., WinRAR, 7-Zip).
Look for the ppt folder which contains all the slides and media files.
b. Recover from Temp Files
PowerPoint may save temporary versions of your file:
Look for files with the extension .tmp in the folder where your original file was saved or in the system’s temporary folder.
Rename the extension from .tmp to .pptx and try opening the file.
7. Professional Data Recovery Services
If none of the above methods work, you might need to consult a professional data recovery service. They have advanced tools and techniques to recover data from severely corrupted files.
a. Finding a Data Recovery Service
Search for local data recovery services.
Look for online reviews and ratings.
Contact them to inquire about their PowerPoint file recovery services.

b. Use Reliable Storage Media
Use high-quality and reliable storage devices to minimize the risk of corruption.
c. Avoid Interruptions
Avoid shutting down your computer or closing PowerPoint abruptly while saving or working on a presentation.
