WordPerfect by Corel is a word processing program. Tags, styles and format coding used in the documents may occasionally cause a WordPerfect file to become corrupt and display an error when you try to open it. This can be very disheartening after you’ve spent time working on that document. The WPLOOK utility available from Corel is included in the WordPerfect Software Developer Kit. This utility can remove the styles and format codes and thus may recover a corrupt document.
