Summary
Microsoft Excel now has a built-in Auto-Recover feature that has replaced the Auto-Save add-in that exists in versions of Excel that are earlier than Microsoft Excel 2002. The Auto-Recover feature saves copies of all open Excel files at a user-definable fixed interval. The files can be recovered if Excel closes unexpectedly, for example, during a power failure.
This article contains an overview of the Auto-Recover feature.

When an Auto-Recover event is triggered
When an Excel file is open and Auto-Recover is turned on, Auto-Recover does not save the file until the first change is made to the file, the Auto-Recover save time interval passes, and Excel has been idle for some time (the default is 30 seconds). After Auto-Recover saves the file, the file is only saved at subsequent save intervals if further changes are made.
When Auto-Recover files are deleted
To keep from filling up your Auto-Recover location with unneeded files, Auto-Recover files are automatically deleted in the following situations:
When the file is manually saved.
The file is saved with a new file name using Save As.
You close the file.
You quit Excel, whether you choose to save the file or not.
You turn off Auto-Recover for the current workbook.
You turn off Auto-Recover by clearing the Save Auto-Recover info every check box.
Auto-Recover save timing
The Auto-Recover timer checks for changed Excel files at the interval you set in the minutes box on the Save tab in the Options dialog box. The timer starts when you start Excel.
Note
In Excel 2007, the minutes box is in the Save category in the Excel Option dialog box. In Excel 2010, the minutes box is in the Save category under File, Options.
When the first save interval passes, Excel checks to see whether any open files have been changed. If Excel locates changed files, an idle timer starts. The purpose of the idle timer is to make sure that the user does not make entries in the worksheet while the save operation occurs. The idle timer restarts each time that the user makes an entry into the worksheet so the Auto-Recover save file is not created until both the save interval passes and no entries are made for the duration of the idle time.
The default idle time is 30 seconds. To change the default idle time, use the AutoRecoverDelay registry key. To do this, follow these steps.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in Windows
Quit Excel if it is running.
Click Start, click Run, type regedit in the Open box, and then click OK.
Locate and then select one of the following registry keys, as appropriate for the version of Excel that you are running.
On the Edit menu, click New, and then click DWORD value.
Type the following name for the new value:
AutoRecoverDelay
Press ENTER.
Right-click the AutoRecoverDelay registry key, and then click Modify.
In the Value data box, type a number between 1 and 600. This is the number of seconds before Auto-Recover tries to save.
When you are finished, click OK.
Quit Registry Editor.
Note
Only manually performed actions in the program affect the idle timer. Formulas that automatically update the file do not affect the idle timer. Excel saves the file when the idle time is reached, between the automatic updates to the formulas.
File formats that are saved by Auto-Recover
Auto-Recover saves all file formats that can be opened in Excel. To maintain speed and simplicity, Auto-Recover saves all files as the current Excel file format, regardless of the original file format opened. The file is saved as a hidden file with an arbitrary filename with the extension '.xar' (for example, ~ar18a.xar).
When you try to save a recovered file upon reopening Excel after it closed unexpectedly, the original file format and name is suggested as the Save file type. Excel stores the original file name and it's related '.xar' file name in the registry for the purpose of recovery.
Auto-Recover and multiple instances of Excel
When more than one instance of Excel is running and one instance closes unexpectedly, a new instance of Excel is automatically started and the Auto-Recover files are opened. If all instances of Excel close unexpectedly, but the computer is still running, a single instance of Excel is started and all Auto-Recover files are opened. In the case of a power outage, all recovered files are opened when you start Excel again.
Compatibility
All Auto-Recover settings, except the Disable Auto-Recover workbook option, are stored in the system registry. Auto-Recover settings are compatible with files from previous versions of Excel is not an issue.
When the Disable Auto-Recover workbook option is set, and the file is opened in an earlier version of Excel, saved, and then reopened in a later version of Excel, the Disable Auto-Recover workbook option is not affected.
