Open GNO File

GNO files are created by the GenoPro free genealogy creation software. These files contain genealogical data for the project and that includes family trees, dates and other relevant information. The application is used to create and share family trees, recording family history and analyze ancestries.

  • If you have a program which can open GNO file installed on your computer then launch that program and select “File” and then “Open” or similar options from its menu to open the GNO file
  • If you don’t have the program installed then you need to try searching for “GNO wiki”, “how to open GNO file” in the search engine.

File extensions are used by Windows operating system to specify what kind of information is stored in the file. Every file in Windows OS needs to have file extension and file extensions are used by Windows to determine which application it should use to open the file. Every application installed on Windows OS places information about which extensions it could open into the Windows registry and Windows uses this information to determine which application it should launch when user double-clicks on the file. If application which can open GNO file is not installed, then Windows will show ‘Windows can’t open GNO file’ message and buttons to either select an application on the computer which can open the file or to search the web for the application which can open GNO file.
