Microsoft PowerPoint allows you to protect your work by using the AutoRecover feature to periodically save a temporary copy of the presentation that you are working on. If the power goes out or your computer stops responding unexpectedly, the AutoRecover feature may be able to recover your work automatically the next time that you start PowerPoint. If you mistakenly quit PowerPoint without saving your presentation, it still may be possible to recover your work, even though the temporary copy has been deleted.
NOTE: Not all presentations can be recovered with this method. For more information about recovering damaged presentations, browse to the Microsoft Knowledge Base articles in the "References" section of this article.

You can set the AutoRecover save interval to occur more frequently than every 10 minutes, which is the default setting. For example, if you set it to save your work every 5 minutes, you can recover more information than if you set it to save your work every 10 minutes.
To turn AutoRecover on, follow these steps:
Recovering Your Presentation When You Quit Without Saving Your WorkWhenever AutoRecover saves a presentation that you are working on, that information is stored in the PPTnnnn.tmp file, where "nnnn" represents random numbers that PowerPoint generates automatically.

It may be possible to recover the PPTnnnn.tmp file if no other data has been made to the hard drive. You may be able to Undelete the PPTnnnn.tmp file. However, if the PPTnnnn.tmp file is recovered, there is no guarantee that it is a good copy of the presentation. To recover the temp file, follow these steps:
