A BMP file is an image file format created by Microsoft in the '80s for use with their Windows operating system. Due to its integral support within Windows and the prevalence of Windows-based computers over the years, the BMP format has become well supported by many image editing applications.


The BMP format is largely considered a legacy format at this point, with designers and digital artists preferring more modern formats such as PNG and JPG for storing and distributing their work.

DDS files are the native image file format used by Microsoft's Direct X gaming API, which was originally developed in the early 2000s as a means for game developers to store texture images in a standard format that are used in 3D game worlds.

The format was enhanced over the years to add lossy and lossless compression and other features applicable to 3D game development. The format has gained some modest support within image editing applications over the years; however, specialist image viewing software is needed to open and display DDS files on many devices.


The primary use for DDS files is in the realm of videogames, in particular those that run on Microsoft Windows-based machines such as PCs. DDS files are used to store imagery that is applied as textured materials to the surfaces of objects within 3D worlds; they can also be used in 2D applications.
