After deleting a few pages in PPT and clicking the save button, you can retrieve the deleted files by clicking the return operation (provided that the file has not been closed, if it has been closed, professional data recovery is required. Try to retrieve it). Specifically, taking PPT2007 as an example, the operation method is as follows:

1. Click a PPT file on the computer to enter.

2. After entering the file, right-click the first slide to delete it.

3. After deleting the slideshow file, click the save button in the upper left corner.

4. At this time, you can click the return drop-down arrow next to Save in the upper left corner and click to delete the slide (that is, undo the deletion operation).

5. You can see that the accidentally deleted PPT page that has not been closed has been retrieved by using the recall function) (at the same time, there are no other operation records in the recall button).
