paul, time stamp?
uuh.
you will end up with zillions of files.
just change:
code:
Copy "C:\new\FIXServer.log" "C:\new\FIXServer@mdayno.@monthno.@year.log"

to:
code:
Copy "C:\new\FIXServer.log" "C:\new\FIXServer@year.@monthno.@mdayno_"+join(split(@time,":"),"").log"

notice, I rechanged your year-month-day order back to what it was.
quess why?
because, once you have lot of those files, they will be automatically listed in correct order according to age.
