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.

What is a PDF/A file?
PDF/A is an ISO-standardized (ISO 19005) variant of the PDF format designed specifically for long-term digital archiving. It embeds all fonts, color profiles, and metadata directly inside the file and prohibits external dependencies, encryption, and JavaScript, ensuring the document will render identically decades from now regardless of which software or fonts are available on the viewing system. It's widely required for legal, government, and institutional record-keeping.
How to open a PDF/A file
PDF/A files open in any standard PDF viewer, including Adobe Acrobat Reader, Apple Preview, and built-in browser PDF viewers, since the format is fully backward-compatible with regular PDF readers. Dedicated archival software such as Adobe Acrobat Pro can also validate that a file meets PDF/A compliance.
