powerpoint automatically saves your presentations to a temporary folder while you are working on them. If you forget to save your changes or if powerpoint crashes, you can restore the file using AutoRecover.
To use AutoRecover:
- Open powerpoint 2013. If autosaved versions of a file are found, the Document Recovery pane will appear.
- Click to open an available file. The presentation will be recovered.
The Document Recovery pane
If you don’t see the file you need, you can browse all autosaved files from Backstage view. Just select the File tab, click Manage Versions, then choose Recover Unsaved Presentations.
