You cannot extract this file on its own. You must download all parts of the sequence (e.g., part01 through the final part) to successfully install the game.
To begin the process, place all parts in the same folder and use a utility like WinRAR or 7-Zip to extract only the first part (part01.rar); the software will automatically join the rest.
