Download something like WinRAR, right click, extract the first part to a folder with the same name as the file, which will automatically do the rest and put everything in a new folder with that name if one does not exist or in an existing one if it does. If there is no option in the right click menu, sometimes WinRAR doesn't pick up that the file is selected, so right click again. Remember that all parts must have the same name up to the . and they must all be in the same place or WinRAR will not pick up the next part as being where it needs to be and will stop extracting.how can i run this file. i downloaded every parts but i cant extract cuz there is no option about extract. all files is rar.
