Convert CWK to DOC

It is unlikely that you can find some converter that can be used to export or convert old Claris documents (.cwk) to older Microsoft Word format (.doc).  The best way to access these .cwk files on some old Mac and save them to some common format like TXT and RTF, which you can then transfer to Microsoft Word and save as doc.

You can also find a utility called icWord that can be used for direct conversion of cwk to doc on Mac.
