What is a DOC file?
The DOC extension refers to the proprietary binary file format used by Microsoft Word versions 97 through 2003. It is structured around the Object Linking and Embedding (OLE) Compound File Binary (CFB) format, acting as a file system within a file that manages streams and storages for text, formatting, scripts, and metadata. Unlike modern XML-based alternatives, DOC files store data in binary records, which can make parsing complex and prone to corruption if the binary headers are damaged.
How to open a DOC file
Microsoft Word remains the primary software for full-feature support of the DOC binary format. However, owing to its ubiquity, most third-party word processors including LibreOffice Writer, Apache OpenOffice, and Corel WordPerfect provide reverse-engineered support for opening and editing these files. Google Docs also offers import capabilities, though complex formatting utilizing legacy OLE objects may experience rendering shifts during conversion.

What is a PDB file?
In the context of eBooks, the PDB (Palm Database) format is a sequential record-based container originally engineered for the Palm OS platform. The file structure consists of a fixed-length header containing metadata (such as Type and Creator IDs) followed by a list of record offsets and the raw data records. For digital reading, these records typically contain text compressed via the PalmDOC (LZ77) or zTXT algorithms, effectively acting as a wrapper for eReader content.
How to open a PDB file
Modern desktop operating systems do not include native handlers for Palm OS databases. Users looking to access eBook content within PDB files should use Calibre or STDU Viewer, which can interpret the specific PalmDOC compression. Note that PDB is also an extension for 'Program Database' debug files in Visual Studio; these are binary disparate and require Microsoft development tools, not eBook readers.
