What is a WSD file?
Document created by WordStar, a word processing program for DOS used heavily in the 1980s; contains document data and page layout formatting; used to store text using the WYSIWYG DOS-based editor.
WordStar is no longer developed, supported, or sold and is considered abandonware. However, Corel WordPerfect can still open WSD files (WordStar 2000 1.0 and later).
