The CurrentDirectory parameter specifies the current drive and directory for the child process. The string requires that the current directory resolves to a known path. A user can specify an absolute path or a path relative to the current working directory. If this parameter is NULL, the new process will have the same path as the calling process. This option is provided primarily for shells that must start an application and specify the application's initial drive and working directory.
