What is a DOTM file?
The DOTM format is a Microsoft Word Open XML Macro-Enabled Template introduced with Microsoft Office 2007. Structurally compliant with the ECMA-376 standard, it utilizes ZIP compression to encapsulate XML data structures, separating content, styles, and relationships. Unlike the standard DOTX template, the 'M' designation indicates the explicit authorization to store and execute Visual Basic for Applications (VBA) macros. This distinction is a security feature designed to prevent the accidental execution of malicious scripts in standard templates.
How to open a DOTM file
Microsoft Word (2007 and later) is the primary software for opening and executing macros within DOTM files. On macOS, Microsoft Word for Mac provides equivalent functionality. For non-Microsoft environments, LibreOffice Writer and WPS Office can open DOTM files and render the content, though VBA macro execution compatibility may vary significantly compared to the native Microsoft engine.

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.
