What is a .WP4 file?
The .WP4 file extension is used for documents created by an older version of a word processing program called WordPerfect, specifically version 4.x that was designed for DOS operating systems. This version of WordPerfect was notable for being the first to offer a feature that automatically numbers paragraphs, which was a significant improvement at the time. Because of this and other features, WordPerfect version 4.x became more popular than WordStar, another word processing program that was widely used on DOS systems before WordPerfect took over.
If you have a .WP4 file, it means you have a document that was made using WordPerfect 4.x. To open this type of file today, you can use a modern version of the WordPerfect program, such as Corel WordPerfect 2021. This newer version of WordPerfect is capable of opening .WP4 files, allowing you to view and edit documents created with the older software on current computer systems.
