Genbox Family History uses GRO files to store saved history report options. These files preserve the settings selected for generating a report in the application.
Genbox Family History is available for Microsoft Windows. The format is therefore primarily useful when the associated report settings are being used in that Windows application.
Open the file with Genbox Family History on Microsoft Windows. GRO files are application settings files and are intended to be loaded by Genbox rather than viewed as text.
If opening the file directly does not work, start Genbox Family History and load the saved report options from the program's report settings.
There is no meaningful standalone conversion for a Genbox Family History GRO file. It stores application-specific report settings rather than document content.
To use the settings in another program, recreate the report options manually in that program. If a report itself is needed in another format, generate it in Genbox Family History and export or save the resulting report using the formats that the application provides.
