What is an MRB file?
Bitmap image file containing several different resolutions of an image; includes settings that mark each image for a specific resolution and type of display; prevents graphics from being stretched or appearing too big or small; also helps for mapping colors more accurately on different-looking displays.
MRB files can be created with Microsoft's Multiple Resolution Bitmap Compiler (MRBC) in older Microsoft Windows SDKs. They may also be created in other Microsoft C/C++ software.
MRB image files were often used when compiling help documentation using Microsoft's older help compilers (HC30.EXE, HC31.EXE, HCP.EXE, and HCW.EXE).
NOTE: Because MRB files can contain multiple raw bitmaps, they can become very large in size compared to other compressed images.
