Player files have the extension .gsp. You can double-click on a Player file to open it, or open the Player executable directly (GSPlayer.exe). In the latter case, a screen will be displayed to allow you to open a particular Player file:
The appearance of the Player file when it first opens is a function of whether it has any Dashboards, and options selected by the author.
Note: If the model file from which the Player file was created was password-protected, the Player file will also be password-protected, and the user will need to enter a password to open the file.
