Recover data from a damaged Office file with the help of 7-Zip

This tip is good, but it can be achieved without 7Zip. Newer versions of Windows can natively handle ZIP files in Windows Explorer. So all you have to do is add the ".ZIP" extension to the end of the existing file name.

Then you can continue on with the rest of the TIP, looking for Word.XML and trying other word processors like Libre Office.
