Worksheet Quattro Pro 2 for DOS (.wq2)
The WQ2 file extension, used by Quattro Pro for DOS, stands for "Worksheet Quattro Pro 2". It represents a spreadsheet file containing data organized in rows and columns, including formulas and charts. Introduced in the early 1990s, WQ2 files replaced the earlier WQ1 format in Quattro Pro versions 5.0 and 5.5. Although no longer widely supported, these files can be opened with older versions of Quattro Pro or Microsoft Excel, or converted to more modern formats like XLS.
