WordPerfect Document (.wpd)
The WPD file extension stands for WordPerfect Document, a proprietary format used by Corel's WordPerfect word processing software. Introduced in 1980 by Satellite Systems International, WPD files can contain formatted text, tables, charts, images, and other objects. Primarily used in business, academic, and home environments, WPD files offer a versatile solution for creating documents like letters, resumes, and newsletters. Over the years, WordPerfect has been acquired by Novell and later by Corel Corporation, ensuring its continued evolution and support.
