  • System infected with the virus.
  • Abruptly shutdown of the system.

Free methods to repair corrupt MS PowerPoint files

PowerPoint files can become corrupted in two different scenarios: either you can open the PPT file, or you cannot. If you can open a corrupted PowerPoint file, you can attempt to repair it using free manual methods. However, if the file cannot be opened, you will need to opt for a professional solution. This blog discusses both manual and professional methods to address a corrupt PowerPoint file.

Method 1: Try moving the file to a new location

  • In case you wish to open the PPT file stored in an external hard drive or a removable storage device, copy the file to your PC’s internal hard drive and then open it.
  • (Note: Nonetheless, if the damaged presentation file resides on the system’s internal hard drive, you should duplicate it to an external drive before attempting to open it. During the copying process, ensure that you also include any embedded images, videos, or other media files within the PowerPoint presentation.)

  • If you are wondering ‘why?’ The purpose is to skip the corruption in your storage device, which is likely preventing you from accessing your PowerPoint file.
  • Moreover, if your storage drive or location is facing an issue, this step is probably going to resolve the problem.
  • Remember to scan and repair the former disk if you are able to open your presentation file after having moved it to the second drive.

In Windows: Open Computer, on the left pane; Click on MY PC and then right-click on the disk responsible for the issues. Then click Properties>Tools tab > click on Check Now, that is available under the Error Checking section. Also, do make sure to check both options. Click on Start to repair PowerPoint file.

In Mac: Here, first, go to the “utilities” folder and then open Disk Utility. Try and attempt to open the disk, which is causing a problem on the left pane. Click on First-Aid and wait till the scan is complete.

For example, If the PowerPoint file is currently saved on your hard drive, consider copying it to an external drive, such as a USB drive. Then, attempt to open the file from the external drive. If the PowerPoint opens without any errors in this location, it indicates that the issue may be related to your hard drive.

Method 2: Insert PPT slides to a new blank PPT

Try inserting the PPT slides into a new blank PPT presentation. To do this, follow the below steps:

  • Launch MS PowerPoint and open a new PPT.
  • Now, from the home tab, select “New Slides” and then select “Reuse Slides” from the drop-down menu.
    select “Reuse Slides” from the drop-down menu
  • Browse the corrupt file that you are unable to open and click on “Insert all.”
  • Save this presentation by pressing “Ctrl + S.
  • To apply the same theme from the corrupt PPT, select the “Design” tab, and click “More,” and select “Browse for themes.”
  • Now select the corrupt PPT file and hit “Apply.”

This way the corrupt PPT file can be repaired with new slides.

Method 3: Use “Open and Repair” option
