What is a good way to get file size in bytes using Fortran?

问题

Is there a way to get the filesize in Fortran using Intel Fortran?

I was using stat which works great in gfortran, but it is not available in ifort.

回答1:

INQUIRE(FILE=filename, SIZE=file_size)

filename is a character scalar, file_size is an integer scalar that will be defined with the size of the file in file storage units ("in bytes" on ifort), or -1 if the size cannot be determined.
