.gro File Extension

Developer: Hewlett-Packard
File type: Graphic Object Bitmap
You're here because you have a file that has a file extension ending in .gro. Files with the file extension .gro can only be launched by certain applications. It's possible that .gro files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is 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.

how to open a .gro file?

Launch a .gro file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .gro file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .gro files aren't yet associated with it. In this case, when you try to open a .gro file, you can tell Windows which application is the correct one for that file. From then on, opening a  .gro file will open the correct application.

applications that open a .gro file



Considered as image viewer software, XnView allows users to manage data and tools for various applications. It is designed for photo and video viewing, converting, or sharing, as well as data creation like contact sheet, slideshow and pages for HTML. This product supports a variety of file formats from 400 readable images to 50 writable images, which are mostly standard such as PNG, JPEG and TIFF for photos, plus WAV, MP3 and WMA for audios, and MPEG for video. Other tools integrated include adjustment or editing of photos through filters, effects, color enhancement, size reduction, and rotation. With this program, audio and video files are available for ripping or burning to CDs and DVD too, but Nero Burning ROM is needed so that must be installed on the same computer you are using. Versions of this software are XnView MP, XnConvert, XnView Photo Fx, XnView Retro, XnView Sketch, XnView Pocket, and XnView Deluxe.

a word of warning

Be careful not to rename the extension on .gro files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .gro. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
