Convert CWK to TXT MARKDOWNMMD

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 MultiMarkdown Documentation (MMD), stored with a TXT file extension, is designed for text documents formatted in MultiMarkdown syntax. The MMD format streamlines the conversion of plain text into various formats such as HTML, PDF, and LaTeX, essential for professional documentation. Introduced in 2005 by Fletcher T. Penney, MMD enhances traditional Markdown by supporting additional features like tables, footnotes, and citations, optimizing documents for better readability and usability in diverse technical environments.
