What AutoRecover Saves

• ✓ Formulas and calculations

• ✓ Charts and shapes
• ✓ Images and objects
• ✓ Cell comments
• ✗ Doesn’t save unsaved file as original (saves as temporary file)
• ✗ Only saves if AutoRecover enabled

Limitations of AutoRecover

• AutoRecover stops working if Excel crashes before auto-save interval
• Computer power loss between auto-save intervals means loss
• AutoRecover files deleted if computer restored to earlier state
• Temporary files cleanup during system updates may delete recovery files
• AutoRecover only useful for current session—not for old deleted files
