The C4 file type, associated with the Edmics format, is primarily used to store raster image data, particularly in the context of engineering and document imaging applications. Edmics C4 files are optimized for efficient storage and retrieval of scanned documents, such as blueprints, maps, and technical drawings, allowing for high compression rates without significant loss of image quality. This format is designed to support the needs of document management systems by enabling easy sharing and archiving of detailed images. The C4 file extension ensures that these images are accessible and manageable across various platforms and devices used in professional environments.
