Restoring a company file in QuickBooks Desktop is a quick way to recover lost or corrupted data. Go to “File,” choose “Open or Restore Company,” then select “Restore a Backup Copy.” Follow the prompts and locate your backup file (.qbb) from your storage device. QuickBooks will guide you through restoring it to the right location. Always double-check that you’re restoring the correct version to avoid overwriting recent work. This process makes data recovery hassle-free.
