About formats

WPS is the document format of Microsoft Works, an integrated productivity suite first released in 1987 that bundled a word processor, spreadsheet, and database in a single affordable application. The WPS format stores word processing documents in a compact binary structure that encodes text content, character and paragraph formatting, page layout, headers, footers, and embedded images. Microsoft positioned Works as a consumer-grade alternative to the more expensive and feature-rich Microsoft Office, pre-installing it on millions of OEM personal computers throughout the 1990s and 2000s. This widespread bundling made WPS one of the most commonly encountered document formats in the consumer PC market, even though many users were unaware they were not using "full" Microsoft Word. The format supports basic word processing features including fonts, text alignment, indentation, bulleted and numbered lists, tables, and page formatting, but lacks advanced capabilities like tracked changes, macros, and complex styles found in DOC. One advantage was accessibility — Microsoft Works cost a fraction of Office's price and came free with many PCs, providing capable word processing to millions of home users and students who did not need enterprise features. Microsoft discontinued Works in 2009, recommending migration to Word or the free Office Online tools. WPS files remain present in personal document archives from that era and can be opened by LibreOffice and older versions of Microsoft Office.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
