What is a POTX file?
The POTX file is the standard XML-based template format for Microsoft PowerPoint 2007 and later, standardized under ECMA-376 and ISO/IEC 29500. It uses ZIP compression to package XML data structures describing slide layouts, themes, and master slides. Unlike POTM, the POTX architecture strictly prohibits the inclusion of VBA macros, making it a safer alternative for distributing design standards without security risks.
How to open a POTX file
POTX files are the default template standard for modern presentation software. Microsoft PowerPoint provides full native support. Alternatively, users on non-Windows platforms can utilize Apple Keynote (macOS), Google Slides (web-based), or LibreOffice Impress, all of which accurately interpret the OOXML schema for editing and playback.

What is a BMP file?
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.
