Microsoft Flight Simulator X is a civil aircraft simulation game from Microsoft for Microsoft Windows. Its GRA files store various game data used by the simulator.
The GRA format is proprietary and is intended for use by the game itself.
GRA files are opened by Microsoft Flight Simulator X on Microsoft Windows. The simulator normally reads them automatically when they are in the location expected by the game installation.
There is usually no reason to open a GRA file directly, and changing or moving one may prevent the simulator from using the associated game data.
GRA files are proprietary game-data files and cannot generally be converted to a useful standard format. Microsoft Flight Simulator X does not provide a general-purpose GRA export function.

The GRA file extension has been reported as being used for an older OpenGL-related object graphic document format. The files contain graphical object information rather than a general-purpose image.
OpenGL itself is a graphics programming interface and does not define a widely used standard document format with the GRA extension. This format appears to be software-specific and may no longer be in active use.
OpenGL libraries do not normally open document files directly. Try opening the file with the original OpenGL-related software that created it.
No reliable general-purpose converter is known for this legacy OpenGL object graphic format. If the original software can still open the file, it may provide an export option, but conversion depends on that software.
