PSP file format is associated with PaintShop Pro, an image editing software developed by Corel. It is a proprietary format used for storing raster graphics created and manipulated within PaintShop Pro. PSP files support layers, channels, and various other advanced graphics elements, allowing for detailed and complex image editing. This format is primarily used for saving intermediate edits, enabling users to continue working on their projects with all elements intact.
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.
