Since you didn't escape your backslashes in the double quoted string, I would guess that is created a file called gppgppgpp in your whatever directory you rand the program in (or c:\ i'm not sure).
Try "c:\\gpp\\gpp\\gpp" Update: using warnings would have told you that an unknown escape \g was being used.
