What is a .MRB file?
The .MRB file extension stands for Multiple Resolution Bitmap File. This type of file is a bitmap image file that contains several different resolutions of the same image. This means that inside one .MRB file, there are multiple versions of an image, each designed to look good on different types of screens or displays. This is useful because it prevents the image from looking stretched, too big, or too small when viewed on various devices. Additionally, .MRB files help ensure that colors appear consistent and accurate across different screens.
These files can be opened using Microsoft Visual C++. If you need to create or modify .MRB files, you can use tools like the Multiple Resolution Bitmap Compiler (MRBC), which was available in older Microsoft Windows Software Development Kits (SDKs). Developers might have also used other Microsoft C/C++ software to work with .MRB files. Historically, these files were commonly used in creating help documentation with Microsoft's older help compilers, such as HC30.EXE, HC31.EXE, HCP.EXE, and HCW.EXE.
It's important to note that because .MRB files contain multiple images, they can be quite large in size compared to other image files that are compressed. This means they might take up more space on your computer or device.
