Could someone tell me what the name of the flat data files are and where they are.
There are lots of them, by all sorts of names in numerous different directories depending on what CalendarScript data they're holding. Basically if you save the whole /calendarscript/ directory structure and files therein you should have them.
Calendar. pl is using 99% CPU when it runs now so the support folks at our hosting site have turned it off.
Have you tried replacing it with a fresh copy and/or seeing whom/what is running it? Maybe Google or Yahoo!, etc. is spidering it in their usual thorough and relentless way?
