Convert PDB EBOOK to MDOWN

The PDB (Palm Database) file extension, associated with PalmDoc eBooks, is a format used for storing eBooks on Palm OS devices. Originating from AportisDoc, PalmDoc files are plain ASCII text compressed using Run-Length Encoding (RLE) to save memory space. These files are decompressed on the fly by PalmDoc readers, facilitating efficient storage and quick access. The PDB format, with its Creator ID and Type attributes, ensures compatibility across various Palm applications, making it a versatile choice for eBook distribution on Palm devices.

The MDOWN file extension stands for "Markdown Documentation". It is used for files written in Markdown, a lightweight markup language with plain-text formatting syntax designed by John Gruber and Aaron Swartz in 2004. MDOWN files are commonly employed in software development to create readable and editable documentation, leveraging Markdown's simplicity for formatting text, lists, code blocks, and links. The historical significance of MDOWN lies in its facilitation of seamless documentation, enhancing clarity and accessibility across various platforms while remaining developer-friendly.
