Quattro Pro
From Just Solve the File Format Problem
Quattro Pro is a spreadsheet program. Originally developed by Borland, current releases are sold by Corel.
The following spreadsheet formats are associated with Quattro Pro:
- WQ1 Quattro Pro for DOS, versions 1-4
- WQ2 Quattro Pro for DOS, versions 5.0 and 5.5
- WB1 Quattro Pro for Windows, versions 1.0 and 5.0
- WB2 Quattro Pro for Windows, version 6.0
- WB3 Quattro Pro for Windows, versions 7 and 8
- QPW Quattro Pro versions 9, 10, 11, 12, X3 and X4
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.
