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 MOBI file?
The Mobipocket eBook format (MOBI) is a binary distribution format developed by Mobipocket SA in 2000, utilizing the Open eBook (OEB) standard and XHTML for reflowable content layout. Encapsulated within a Palm Database (PDB) container, MOBI files employ either the LZ77-based PalmDOC compression or the proprietary HUFF/CDIC algorithm to minimize file size. The format supports Digital Rights Management (DRM), metadata indexing, and javascript capabilities, serving as the foundational architecture for Amazon's proprietary AZW format before the adoption of KF8.
How to open a MOBI file
Native support for MOBI is restricted primarily to Amazon Kindle hardware and legacy Mobipocket readers. On Windows, macOS, and Linux, users require third-party eBook management software such as Calibre, which offers comprehensive viewing and conversion capabilities. Alternatively, the Kindle Previewer tool provided by Amazon or multi-format readers like FBReader and Sumatra PDF can render the unencrypted content of these archives.
