Well I'm answering my own question. I used Getenv("systemdrive") char * BUFF; BUFF = getenv ("SYSTEMDRIVE"); strcat( BUFF, "\\whatever\\Register.bat"); This produced C:\whatever\register.bat

Is there a C++ funtion like GetSystemDrive? Basically what I want is a way to get the system drive letter into a string. This is sort of like What I want to do. char BUFF[MAX_PATH] = {NULL}; GetWindowsDirectory(BUFF, MAX_PATH); strcat(BUFF, "\\whatever\\Register.bat"); That would create a string "C:\windows\whatever\Register.bat" What I really want is to create a string like this "C:\whatever\Register.bat" I just need a way to get the systems drive letter. Any help would be appreciated.
