Convert PDB EBOOK to MS

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 MS file extension, short for "Manuscript", is associated with the roff (runoff) document formatting system used in Unix-like operating systems. It is part of the GNU roff (groff) implementation, which formats documents such as letters, memoranda, reports, and books. Historically, it evolved from the Multics runoff system in the 1960s and became integral to Unix documentation. The MS macro package supports features like cover pages, table of contents, numbered headings, and multi-column layouts.
