So today I had a good friend call me with what turned out to be quite a typical situation. She was working tirelessly on her computer (a brand new macbook, for the record), and for some reason did not click save inside Microsoft Word. Low and behold, when she came back to her computer, the file was no where to be seen and all of her work was gone.
We have all lost work like this, and, although at the time its terrible, its actually (for the most part) preventable. Microsoft Word, as well as all of the other Microsoft Office applications have built it security options for situations just like this. Basically, Word can save your documents for you automatically at any time interval. These settings can be found in Word (or Excel, or Powerpoint) preferences, under the save tab. Just make sure to change the AutoRecover time interval to one minute and to check the box that says Always Create Backup Copy. Below is the screenshot of the window on a mac, though it should look very similar in Windows.
Also, while youre at it, make sure under the File Locations tab you add a location for AutoRecover files. That way, if you do lose a document, you will know where Word automatically saved it. Hope this helps!
