The WQ2 file format is a legacy spreadsheet document structure created by Borland for use with Quattro Pro for DOS version 5.0. It serves as a container for financial data, mathematical formulas, and organizational tables within the historical Quattro Pro productivity suite. Although now largely obsolete due to the dominance of modern office standards, these files are considered safe and remain relevant for archival recovery or data migration projects.
