Software support
Microsoft Excel dropped support for all Quattro Pro formats 2010. A 2014 test with the (then current) Quattro Pro X7 showed that even though the software was still able to reads all formats, the support of the DOS formats had some limitations[1]. As of 2025, LibreOffice Calc can read Quattro Pro for DOS and Quattro Pro for Windows (version 6.0) files[2]. A 2025 update of the earlier 2014 test did reveal some limitations though, which are mainly related to handling of cached formula results, and compatibility issues between some native Quattro Pro functions and their LibreOffice Calc counterparts[3].
Sounds
Starting with Quattro Pro 3.0 you could create slide shows which included sounds. The sound files start with STEVE.H and usually have a .SND extension.
