Corel WordPerfect, developed by Corel Corporation, is a word-processing application included in the Corel WordPerfect Office suite. Some older versions of WordPerfect for Microsoft Windows used the .wkb file extension for document files.
The format is no longer the standard WordPerfect document format. Newer versions generally use the wpd instead, so .wkb files are now mainly encountered as legacy documents.
Open the file with Corel WordPerfect or Corel WordPerfect Office for Microsoft Windows. Because .wkb is a legacy format, a compatible older version of WordPerfect may be required if a current version does not recognize it.
If WordPerfect opens the file, use its Save As or export command to save a copy in the current WordPerfect document format, usually a .wpd file, or in another format supported by that version.
There is no need for a separate converter when a compatible version of WordPerfect can read the document. If the file cannot be opened, conversion may not be possible without an older WordPerfect installation.
