.CWK is ClarisWorks Document

A CWK file is a document created by Apple's AppleWorks or ClarisWorks productivity suite. It may store a word processing document, spreadsheet, or presentation. CWK files were replaced by .PAGES, .KEY, and .NUMBERS files created with iWork applications.

Apple acquired ClarisWorks in 1998 and renamed it to AppleWorks. Both productivity suites were available in Mac and Windows versions. However, AppleWorks has been discontinued and was last updated in 2004.
