WordPerfect WPDReader is a tool used to open and view Word Perfect files. A Word Perfect file (WPD) is a very old file type that few people use anymore. People who have old WPD files may have a hard time opening the files, and that is why the WordPerfect WPDReader was created. It allows you to view files and then convert them to PDF files. This tool costs money, whereas other programs such as LibreOffice will open files for free. However, you have to download and install the entire writing suite, whereas with the WordPerfect WPDReader tool is small and very quick to install.
