Question: What is an GRH File?
Have you found, downloaded or received an GRH file, but don't know which software program is required to open it?
Before attempting to open an GRH file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.
Answer: Files which are given the .GRH extension are known as Quickbasic image files, however other file types may also use this extension. If you are aware of any additional file formats that use the GRH extension, please let us know.
The best way to open an GRH file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the GRH file.
Tip: Try to open the GRH file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.
well i came across this .grh file today. I renamed it to .rar and I was able to extract it and get files out of the rar file.
