The .wwb file extension is associated with Corel WordPerfect, a word-processing program developed by Corel Corporation. WordPerfect is also included in the Corel WordPerfect Office suite.
These files store the configuration of button bars used in the Windows versions of Corel WordPerfect, including the buttons and related settings that make up a customized bar. The file works as part of WordPerfect's user-interface configuration and is not a standalone document format.
Use Corel WordPerfect or Corel WordPerfect Office for Microsoft Windows to use a .wwb file. The file is normally loaded through WordPerfect's button-bar customization or settings features rather than opened as a document.
A .wwb file stores WordPerfect button-bar settings rather than document content, so it is normally retained for use in WordPerfect instead of converted to a document format.
The button bar can be recreated manually in WordPerfect's customization tools if needed.
