Convert WPD to RTF

Corel WordPerfect documents (.wpd files) can be easily resaved to RTF (Rich Text Format) by simply using the File ► Save as.. function found in the program. But except for that, such wpd to rtf conversion can be done with almost any word processor that supports WPD document, because RTF format is supported in all of them. Only the text with some basic formatting will be preserved.
