What is a .dtm file?

File extension details and usage information

The .dtm file extension is associated with Deluxe Paint, a raster graphics editor developed by Electronic Arts in the mid-1980s. It was a popular tool for creating and editing images, particularly on the Amiga platform. DTM files store bitmap images, often with indexed color palettes. The format was designed to be efficient for the hardware of the time, allowing for relatively complex images to be displayed and manipulated. While not as widely used today, DTM files represent a significant part of early digital art history. They often contain pixel art, animations, and other graphics created for games and applications of that era. The format supports various color depths and resolutions, depending on the version of Deluxe Paint used. Due to its age, specialized software is typically required to open and view DTM files, as modern image editors rarely offer native support.
