Lost an Important File? Here’s How You Go About Recovering It.

Important note, this may not always work but it's worth a try. 

Many people don’t realize how easy it is to accidentally hit Don’t Save when they close a program. A reflexive move such as this can make hours of hard work disappear. As a reasonable assurance against such accidents, applications like Microsoft Word automatically save changes to documents at regular intervals (on Word, the function is called AutoRecover). You can minimize any loss of data by simply shortening the AutoRecover interval. In Microsoft Word 2013 you do this by going to File --> Options --> Save --> Save Autorecover information every ___ Minutes. Choose the interval you wish to have.  Then click OK.  

To recover the file  you can click on the Open tab on the side of the screen and scroll all the way to the bottom of the page and select "Recover Unsaved Documents".
