Hello, EBENEZER YONG
Welcome to the Microsoft community.
I realized that you have encountered a problem with recovering an PowerPoint file. I understand how difficult it is to lose important data.
I notice that you posted in iPhone or iPad section. I would like to know where this file is stored?
1 -> If it's stored in OneDrive, you can try:
- Search for your files in the OneDrive online. If you can find the file, right-click it and select "Version history". See if an earlier version has all 93 slides and recover it.
- Look in the Recycle Bin. Visit OneDrive online. On the left side of this page, select Recycle Bin. If you find the PowerPoint file, select it and choose Restore.
- If you're a Microsoft 365 subscriber, you can use OneDrive's file recovery feature to undo all the actions you've taken on photos and folders in the last 30 days. For step-by-step instructions, see: Restore your OneDrive - Microsoft Support
- If the above steps don't work, I sincerely recommend contacting OneDrive email support. The support agent may help you recover the file. To contact: Log in OneDrive online, then click this link: Email OneDrive Support. Or you can click the feedback button in the upper-right corner.
2 -> If it is stored locally on the iPad or iPhone device, you can try searching in the device and see if there is temporary file containing the contents of the slide.
3 -> If you have saved them in a third-party cloud storage such as iCloud, I suggest you look for the corresponding file recovery method of the software.
4 -> If the above methods don't help you recover your files, I sincerely suggest you consider using third-party data recovery software or seek the help of a third-party data recovery company.
I can only imagine how difficult this must be for you. I sincerely hope that you will have the chance to recover the important data. Thank you for your understanding and cooperation.
Best wishes,
