@Tom: Thank you a lot. I will test it. Please, what 's about the output wanted. If I want to have this output /Z1/Z2/Z3/REP/dir1                       /dir2                       /dir3                        /dirn   So what's about the time of treatement  for a big file (more than 5 GB) ? It will be very quickly ? I know that's we can read a zip file in sas, but the aim ,here, is to have the output REP/dir1,......REP/dirn Thank you         ... View more
