About formats

CDT (CorelDRAW Template) is a template file format used by CorelDRAW, Corel Corporation's vector graphics editor available since January 1989. A CDT file is structurally identical to a standard CDR document — sharing the same RIFF-based container, vector object types, color definitions, and page layout capabilities — but is designated as a reusable starting point for new designs rather than a finished artwork file. When opened in CorelDRAW, a CDT creates a new untitled document pre-populated with the template's content, leaving the original template unchanged for repeated use. This workflow mirrors the template model found in office productivity suites, adapted for graphic design. CDT files commonly contain pre-built layouts for business cards, brochures, letterheads, certificates, posters, and other standardized print materials, complete with placeholder text, guide lines, bleed areas, and properly configured color spaces for print output. One advantage is workflow consistency — design teams can distribute branded templates ensuring every new document starts with correct dimensions, margins, fonts, and color palettes aligned to corporate identity standards. The format also saves significant setup time: rather than configuring document properties and recreating layout elements from scratch, designers begin with a production-ready foundation. Corel ships hundreds of CDT templates with CorelDRAW installations, and the format is supported across CorelDRAW versions with the same compatibility considerations as CDR.

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.
