In Word 2002 or 2003, you can use the "Recover text from any file" file
type in the File|Open dialog box to open a ClarisWorks .cwk file, but
you will only get the text... all of the formatting will be lost.
Earlier versions of Word for Windows do not have the ability to import
native-format .cwk files. From within ClarisWorks, it is possible to
"save as" a Microsoft Word (.doc) or rich text format (.rtf) file, both
of which Word can open. Or you might consider a third-party conversion
program such as Dataviz Conversions Plus (see
http://www.dataviz.com/products/conversionsplus/index.html ).
