Convert CWK to UOT

The CWK file extension stands for ClarisWorks Document, specifically used for word processing documents within ClarisWorks (later AppleWorks). Apple rebranded ClarisWorks to AppleWorks after acquiring Claris in 1998 and discontinued it in 2004. These CWK files have since been largely replaced by formats like PAGES in Apple's iWork suite. Opening CWK word processing files now requires older versions of Apple's Pages.

The UOT (Uniform Office Document) file extension is used for documents created in the Uniform Office Format (UOF), an open standard developed for Chinese office productivity applications. It uses an XML format to describe the document and is compressed to reduce file size. UOT files can be opened by OpenOffice and its variants. The format is similar to the OASIS OpenDocument format but is not compatible with it.
