Why these files stop opening

Modern Word and Excel refuse to open files older than Office 97, and every other 90s office suite is gone. Our converter runs the LibreOffice import filters that were written specifically for these formats - WordPerfect, Works, Lotus, Quattro Pro, ClarisWorks, StarOffice - and saves a clean PDF or Office file.
