.shs files are scrap object files, generally created by MS Office (word, excel etc.)
If you are using Windows XP and MS Office 2003, simply drag and drop that file to MS Word / MS Excel application window.
If you are usnig Windows 7 and MS Office 2007 or later, then change the extension of .shs file to .docx and open it with MS Word. It will give you an error message and then will ask you to extract content. Click yes, and you are done.
