The main OpenTTD directories can be found in various locations, depending on

your operating system:

    1. The current working directory (from where you started OpenTTD)

        For non-Windows operating systems OpenTTD will not scan for files in this

        directory if it is your personal directory, i.e. '~/', or when it is the

        root directory, i.e. '/'.

    2. Your personal directory

        Windows: C:\My Documents\OpenTTD (95, 98, ME)

                 C:\Documents and Settings\<username>\My Documents\OpenTTD (2000, XP)

                 C:\Users\<username>\Documents\OpenTTD (Vista, 7)

        Mac OSX: ~/Documents/OpenTTD

        Linux:   $XDG_DATA_HOME/openttd which is usually ~/.local/share/openttd when

                 built with XDG base directory support, otherwise ~/.openttd

    3. The shared directory

        Windows: C:\Documents and Settings\All Users\Shared Documents\OpenTTD (2000, XP)

                 C:\Users\Public\Documents\OpenTTD (Vista, 7)

        Mac OSX: /Library/Application Support/OpenTTD

        Linux:   not available

    4. The binary directory (where the OpenTTD executable is)

        Windows: C:\Program Files\OpenTTD

        Linux:   /usr/games

    5. The installation directory (Linux only)

        Linux:   /usr/share/games/openttd

    6. The application bundle (Mac OSX only)

        It includes the OpenTTD files (grf+lng) and it will work as long as they

        are not touched
