The WordPerfect text and graphics file format is a proprietary document specification developed by the WordPerfect Corporation for its version 5.x software suite. It was primarily utilized for generating complex business reports, legal documentation, and manuscripts that required precise formatting control and embedded graphical elements. This legacy format is now considered obsolete, though it is frequently encountered in digital archives and requires specialized conversion tools or legacy-aware productivity suites for data access.
