In attempting to save a lost power point, it will be reliable depending on whether AutoRecover is on or off. Drafts are usually saved in the background by PowerPoint, and when the program crashes or unexpectedly shuts down, the drafts are saved to be restored. These normally appear in a recovery panel when reopening PowerPoint. It is also possible to search the unsaved presentations location manually. This feature does not guarantee it, but in most cases, you’ll be able to recover an unsaved PowerPoint file.
