What is a .12m file?

The .12m file extension is associated with ImageWorks, a graphics software suite popular in the 1990s, particularly for its image editing capabilities. These files typically store raster image data, often used for graphics in applications or presentations from that era. While not widely used today, they might still be encountered in archives of older digital art or design projects. Understanding the .12m format is mainly relevant for historical preservation or when working with legacy graphic assets. Specialized software or converters might be needed to access and view these images on modern systems.
