About formats

TXT (Plain Text) is the most fundamental digital document format, storing unformatted text as a sequence of character codes with no embedded styling, layout instructions, or metadata beyond the characters themselves. The foundation of plain text computing traces to the ASCII standard published in 1963 by the American Standards Association (now ANSI), which defined 128 character codes including uppercase and lowercase Latin letters, digits, punctuation, and control characters. Modern plain text files typically use UTF-8 encoding, a variable-width Unicode scheme that encompasses virtually every writing system worldwide while maintaining backward compatibility with ASCII. Line endings vary by platform convention — LF on Unix/macOS, CR+LF on Windows — though most contemporary tools handle both transparently. One advantage is absolute universality — TXT files can be created, read, and edited on every computing device ever manufactured, from 1960s mainframes to modern smartphones, without any specialized software. The minimal overhead is another core strength: plain text carries zero formatting baggage, making TXT files ideal for configuration files, log output, data interchange, source code, scripts, and any context where content must be processed programmatically. Plain text serves as the substrate for structured formats like CSV, JSON, XML, YAML, and Markdown, and remains the input/output medium for virtually all command-line tools and programming environments. Despite decades of richer alternatives, TXT endures as the one truly universal document format.

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.
