What is a .GROB file?
A .GROB file is a type of picture file known as a Graphic Object Bitmap File. It's a special kind of image that is made using a Hewlett-Packard (HP) scientific graphing calculator, like the HP-48 or HP-49 models. These calculators are often used by people who work with math, science, or engineering because they can create detailed graphs and charts. The .GROB file can hold a picture of a graph, chart, or any other visual that someone has made on their calculator.
To view or work with a .GROB file on a computer, you can use programs like Emu48 or XnViewMP. Emu48 is an emulator, which means it can mimic the HP calculator on your computer, letting you open and interact with .GROB files as if you were using the calculator itself. XnViewMP is a more general image viewer that supports a wide range of image formats, including .GROB files, so you can open and view these images on your computer.
It's also worth noting that while we're talking about .GROB files, they might sometimes be referred to with a .GRO extension. It's essentially the same thing, just a shorter way of naming the file. Whether you see .GROB or .GRO, the file is a Graphic Object Bitmap created on an HP graphing calculator.
