Click "Start" and "Computer" to locate the default folder for the game on your computer's hard drive. Typically, game folders are found on the "C" drive in the "Program Files" folder. If you're not sure of the game files location, click "Start" and enter "Indiana Jones" in the "Search programs and files" box. Click the game folder to access the game files.
Click the "Levels" subfolder to see the files for each level. Click the "ropetest.exe" and "whipgym.exe" files to play each of the bonus levels. If you're having trouble finding these files or this particular folder, use the "Search" option again and look for either "ropetest" or "whipgym."
