Help protect your files in case of a crash
Crashes happen. The power goes out. And sometimes, people accidentally close a file without saving. To avoid losing all your work when stuff like that happens, make sure AutoRecover and AutoSave are turned on.
Click File > Options > Save.
Make sure the Save AutoRecover information every x minutes box is selected.
In Word, Excel, and PowerPoint, make sure the Keep the last autosaved version if I close without saving box is selected.
Important The Save button is still your best friend. To be sure you don’t lose your latest work, click Save (or press Ctrl+S) often.
To be extra safe, enter a small number in the minutes box, like 10. That way, you’ll never lose more than 10 minutes of work.
On the other hand, if you want to make Office faster, try entering a larger number in the minutes box, like 20.
AutoRecover saves more than your files. It also saves your workspace (if it can). Suppose you open several spreadsheets in Excel and the power goes out. When you restart Excel, AutoRecover tries to open your spreadsheets again, laid out the way they were before, with the same cells selected.
In Word, Excel, and PowerPoint, use AutoRecover to recover an Office file.
