This is a format for storing graphical information, created in the CorelDRAW program. It can contain raster and vector images. It’s used exclusively in vector editors from the Corel company. For use in third-party software it’s necessary to use converters. Version 10 and earlier can be opened in vector software from Adobe. CDR can be opened also with the help of Inkscape and sK1 programs.
This format is used to store background images in uncompressed form in the X Windows System user interface for remote server maintenance. It stores a 'dump' or screenshot of the window or background of the client program. It may include different colors depending on the capabilities of the graphics card that is used to create the XWD file.
