What is a DOT file?
The DOT file extension represents a legacy Microsoft Word Document Template utilized by Word 97 through 2003. Based on the proprietary Microsoft Object Linking and Embedding (OLE2) binary interchange format, DOT files store structural blueprints-including styles, AutoText entries, macros, and toolbar customizations-to standardize document creation. Unlike the modern XML-based Office Open XML standard, DOT relies on binary sector storage streams and acts as the predecessor to the DOTX and DOTM formats. These files are susceptible to macro viruses due to their ability to execute embedded Visual Basic for Applications (VBA) scripts.
How to open a DOT file
Native support for DOT files is embedded in all versions of Microsoft Word, though modern iterations (Word 2007 and later) will open them in Compatibility Mode. For users without a Microsoft Office license, the format can be parsed by open-source office suites such as Apache OpenOffice Writer and LibreOffice Writer. Google Docs also provides conversion capabilities for viewing and editing DOT contents within a web browser environment.

What is a DOTX file?
A DOTX file is a template created by Microsoft Word 2007 and later, adhering to the Office Open XML (OOXML) standard standardized by ISO/IEC 29500. It serves as a non-macro-enabled baseline for generating .DOCX documents, containing pre-defined layouts, styles, fonts, and images. The format functions as a ZIP-compressed package of XML files. Crucially, DOTX files explicitly restrict the storage of Visual Basic for Applications (VBA) code; any attempt to save macros results in a forced conversion to the DOTM format.
How to open a DOTX file
Microsoft Word is the standard application for editing DOTX templates. Because the format is an open standard (OOXML), it enjoys broad compatibility across third-party platforms. macOS users can utilize Apple Pages (which imports DOTX formatting), while Linux and Windows users can rely on LibreOffice Writer or SoftMaker FreeOffice. Cloud-based platforms like Google Workspace also support native import and conversion of DOTX templates.
