Software support
As of 2014, the Quattro Pro formats aren't well supported. Microsoft Excel dropped support for all the above formats in Excel 2010, whereas LibreOffice and OpenOffice only support Quattro Pro for Windows, version 6.0 files. Quattro Pro itself (which is now part of the WordPerfect Office suite) still reads all formats, although support of the DOS formats has some limitations. See this blog post for more details.
