The Quick Way to Open Files with G3W Extension

Different software packages use different file extensions, so if you can't open the G3W file, it could be because:

  • You don't have the associated software on your computer (Geoplan-Geospace is the most popular software package that uses G3W file).

  • You may have Geoplan-Geospace but your computer is not configured to associate G3W files with the relevant software.

  • The file is corrupt.

If You Don't Have Geoplan-Geospace

In order to open your G3W file, you will have to download Geoplan-Geospace or another similar software package.

If Your Computer is Not Configured to Open G3W Files

If you have the relevant software, but your computer still won't open the software, you will have to change the file associations on Windows or Mac. Depending on your operating system, you can ensure that your computer always open G3W files using Geoplan-Geospace or another program of your choice that uses G3W files.

If that still doesn't work, you can get in touch with your software developer to find out what you can do. You can contact any of these developers for more information or assistance:

If the G3W File is Corrupt


In some instances, you may receive an error message stating that the file is corrupt. If you have tried all of the above, and it still doesn't work, download or request a new copy to see if that works.
