What is an OTT file?
An OTT (OpenDocument Text Template) file is a standardized document template defined by the OASIS Open Document Format for Office Applications (ODF) specification (ISO/IEC 26300). Based on XML syntax and encapsulated within a ZIP-compressed container, the format stores styling definitions, page layouts, and manifest files separate from content, allowing users to generate multiple .ODT files with consistent formatting. It supports lossless compression and interoperability across open-source office suites.
How to open an OTT file
Native support is built into ODF-compliant word processors such as LibreOffice Writer and Apache OpenOffice. Microsoft Word opens OTT files via integrated ODF conversion filters. Because the file functions as a template, opening it typically instantiates a new, untitled document (.odt) rather than editing the template file itself, unless specifically opened for editing via the application's file menu.

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.
