Where is the "main dolphin folder"?

Every one says go to the main dolphin folder when I google... Um, where is the main dolphin folder then?

it will be something like C:\ProgramFiles(x86)\Dolphin

Don't got one of those. ):

Try just searching on your computer 'Dolphin'. It should be found quite quickly.

Also, do you have a Dolphin shortcut on your desktop? Try right clicking it then select 'open file location'.
