It's every spreadsheet user's worst nightmare – you've worked on a workbook for a period of time, and then accidentally close it without saving. Or the power goes out, or Excel crashes . . . the list of spreadsheet hazards goes on and on.
If you're using Excel 2010 or later, there's a pretty good chance you can mitigate much – but not all – of the risk related to unsaved workbooks. Regardless, in any version of Excel, you can raise the odds of having a recovered copy of your work available after a software crash. As shown in Figure 1, Excel has long had an AutoRecover feature that's designed to help you recover unsaved workbooks should Excel crash.
