Rem rename command is done twice (2) to allow for 1 or 2 digit hour,
Rem If before 10am (1digit) hour, rename starting at location (0) for (2) chars,
Rem will error out, as location (0) will have a space and space is invalid character for file name,
Rem so second rename will be used.
Rem if equal 10am or later (2 digit hour) then first rename will work and second will not
Rem as file2.log will not be found (it is already renamed)
