    the file format and extension of don't match...

    hi.. I recovery my hard and now when we go to open excel file it gives us the error message "The file format and extension of ".xls" don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?"
    file was created in Microsoft Office 2003..
    I would be very grateful if you could guide me in this regard.

    I have tried to recover file but unable to do.
    I think, Reasons behind why Files Become Corrupted.

    >Presence of malware or defect in the software used to manipulate or create the file.
    >Power loss or other power related issues.
    >Improper shutdown such as force shut down or due to power outages.
    >Ejecting the hard drives and other storage media before properly disconnecting them.
    >Bad programming especially if it results in a hard restart.
