5 things which I learnt about sandbox folder structure:

-          Bin 32 & bin 64 are where the executable, game files and the editor also

-          Bin 64 loads faster than Bin 32 and allows us to use more memory

-          Inside the game folder, the actual game is being saved in the .pak files the animation, sounds, noises and the environment are in there which can be opened using winrar, WinZip and can also be unzipped

-          Inside the code folder, scripts can be found so that changes can be made to the game or trailer

-          The editor folder contains files for the sandbox editor and there include icons, material, plugins, scripts etc
