What is a DOTX file?

Office Open XML Template

Developed By
Microsoft Corporation
Initial Release
2007
MIME Type
application/vnd.openxmlformats-officedocument.wordprocessingml.template

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 BMP file?

Bitmap Image File

Developed By
Microsoft
Initial Release
1985
MIME Type
image/bmp

The BMP (Bitmap) format, formally known as the Device Independent Bitmap (DIB) file format, is a raster graphics standard developed by Microsoft for the Windows operating system. The file structure consists of a file header (BITMAPFILEHEADER), an information header (typically BITMAPINFOHEADER), a color table, and the pixel array. Data is stored as a grid of pixels with color depths ranging from 1-bit to 32-bit, typically uncompressed, though the format supports lossless Run-Length Encoding (RLE4 or RLE8) and Huffman 1D compression for specific bit depths.

How to open a BMP file

Due to its simplicity and documentation as a core Windows standard, BMP files possess near-universal compatibility. They can be opened natively by virtually all image viewers and web browsers across Windows, macOS, and Linux without additional software. Standard utilities include Microsoft Paint, Apple Preview, and Windows Photos. For advanced manipulation, pixel-based editors like Adobe Photoshop and CorelDRAW are recommended, though the format is rarely used for complex editing due to its large file size.
