The XCF file format is the native image format used by GIMP (GNU Image Manipulation Program), a free and open-source raster graphics editor used for image editing, free-form drawing, converting between different image formats, and more specialized tasks. XCF stands for eXperimental Computing Facility, which was the name of the lab where GIMP was originally developed. XCF files are designed to store all the information that GIMP needs to accurately render an image.
The BM file type, associated with X11 Bitmap, is a monochrome bitmap image format used on the X Window System, which is commonly found on Unix and Unix-like operating systems. It stores black-and-white images in a plain text format, where each pixel is represented as either on (black) or off (white). These files are often used for simple icons and cursors within the X11 graphical user interface. Due to its simplicity and text-based nature, BM files can be easily edited with standard text editors.
