What is a gro file and how do I open a gro file?

A graphic object bitmap file is implemented with the same raster image compression specifications used for bitmap image files, and encoding standards proprietary to Hewlett-Packard are used for storing these graphic object bitmap files in the GRO format. These GRO files are used by particular models of scientific calculation and computation devices manufactured by Hewlett-Packard. These Hewlett-Packard scientific calculation and computation devices integrated with support for these GRO files include the HP-49 calculator and its predecessor, the HP-48 calculator. The firmware of these devices store digital visual objects and elements like charts and graphs in these GRO files. Users of computers running on Microsoft Windows-based systems can use HP callculator emulators to open and view the data stored in a GRO file. The XNView program is also another Microsoft Windows application that can be used to open files affixed with the .gro extension. These supported devices primarily use these GRO files to reference the data of the GRO file when a user makes changes to the numerical and scientific data associated to the graphs and charts stored in the corresponding GRO file.
