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 an LRF file?
The LRF (Broad Band eBook) format is a deprecated proprietary eBook format developed by Sony for its PRS-500 and PRS-505 e-reader series. It is a binary format that utilizes a specific XML-based markup internally for layout rendering, supporting hard-coded pagination, vector images, and zlib compression. Unlike reflowable formats, LRF defines static page layouts, which can lead to scaling issues on displays with resolutions differing from the original Sony hardware specifications.
How to open an LRF file
Sony has abandoned LRF in favor of the EPUB standard, meaning modern devices do not support it natively. The most reliable method for opening LRF files on desktop systems is using Calibre or the Summoner application. For viewing on modern e-readers or tablets, conversion to EPUB or PDF via Calibre is the standard technical workflow.
