Convert SDW to TEXT MARKDOWNPHPEXTRA

The SDW file extension stands for StarOffice Writer Document, used by the StarOffice Writer software for text documents. Introduced with StarWriter 1.0, SDW files were commonly used in the early 2000s. These files can be opened by modern office suites like Apache OpenOffice with legacy filters installed. SDW files are part of the evolution of document formats leading to today's more standardized formats like ODT.

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.
