Did you mean to ask what size to set the pagefile to? Standard advice is three times
the amount of physical memory installed as a minimum. I remember one person using
a video editing app recommending 10 Gb and they had 2 Gb physical memory installed
on a XP machine. I would expect that having multiple video editing windows open would
use heaps of memory, so that seems good advice to me. Hope this helps. Cheers. Spexx.
