CEL Entries from memory or file

CEL Entries from memory or file

Hi,
My questions are about selection CEL Entries from memory or file in Filter window.
1. Is equal application for “Entries from memory” with “Entries from files” when I select same number for “Size of the ring buffer” (in project properties: Data storage CEL) and “max number” (in Filter window)?
2. What is your recommendation for Size of the ring buffer? which size is better?
3. What happens if number of system message exceed from 32767? Can I access to event before number of 32767? Is there application for .CEL files that produced by zenon when system message exceed from 32767?
4. Is there a way for deleting .CEL files after e.g. one year?

thanks
