1. Click on the PPT file you want to open, and a window will pop up asking you to choose "Repair" or "Cancel".
2. After clicking Cancel, it will not open. After clicking Repair, a window pops up saying it cannot be read, but it still cannot be opened.
3. Select the file, right-click the mouse, and select [Properties].
4. Check [Unlock]. Click [OK] to open successfully.
This is not often encountered, but it is very troublesome when it is encountered. At the same time, this method is also suitable for office software such as WORD and EXCEL. Hurry up and save it for emergency use.
